GT4 Zed

Thanks Steve and guys i hope we can have people conrtibuting their experience, costs etc when making adjustments, swaps to suspension parts and that the traders here can link or advertise their products here too so it is all a one stop info/tutorial thread.

Bushes We all know that the zed out of the box handles very well for DD, fast road and occasional track work but as the start to edge to 40K miles and above the suspension sufer with inability to hold alignment due to the fact that Nissan used so many rubber bushes between varios supension points and as naturally rubber perishes with age or aggressive use and allows play between parts that so have little or no movement al all. Typically you find that the car tramlines alot more and follows all the ruts on the road and excessive bump steer and when you think you have cure the problem with re-alignment it comes back again. These symptoms are worse with lowered cars or runing wider or grippier tyres The chief culprit is the dreaded front compression(banana) arm bush with which commonly goes first. The next is the tranverse link(lower control arm) inner bush which tends to go and once all these are affeected and unchanged the out bushes or spindle will be dammaged next leaving you wih horrible handling and a huge cost. The rear bushes tend to have little issues but because they are too soft means you have squirm and wheel hop especially on acceleration and roll. So replacing them with uprated bushes is necessary if you want a sharp handling car than retaines aligment settings which intend means you have a consistent feel and confidence when opushing on. The problem here is that nissan will only supply the bushes with the arm at great cost and donot sell isolated bushes. Nismo do make so harder uprated bushes but its also costly and will take ages to order. so the only solution is aftermarket which is cheaper than buying oem arms and oem bushes which will invariable perish if you use the car aggresively or lowered. I have done alot of research and as a result want to share some of the options available and provide a forum to discuss individual issues members may have. I have started with bushes and will cover other areas with time. My car is lowered on coilovers and has adjustable suspension on all the key areas for track performance and run on a stiff setup so i can tell you my bushes have had it and i will have to change the lot So in sumary you have the following choices: - Replace worn bushes with new OEM bushes and arm combo at great costs from the stealers. - Buy second hand OEM arms with bushes from the usual suspect (Zmanalex, Lee, Breakers etc)and hope they are in good nick or last. - Buy uprated rubber OEM style bushes and replace worn OEM ones. Nismo, Zmanalex(compression arm bush only i believe) - Buy after market urethane bushes and replace key areas or complete kit. eg whiteline, superpro etc - Buy solid bushes to replace key areas or complete kits. eg SPL, Abbey(compresion arm bush only i believe) The choice of what to go for will depend on what you use the car for, funds, replacement bushing availability. Eg You can replace just the compression arm bush and leave the rest if they are fine with either solid, OEM style bush or urethane and it should be ok but ideally if you wanted precise handling and consistent feel and avoid suspension bind (by mixing) it would be better to use the same bush type all through on the same axle or try and keep the same type on the same axis of the suspension. Eg All inner bushes could replaced with urethane and all outer ones OEM rubber on the same axle. As mentioned before some limitation exist as not all manufactures make all OEM replacement bushing. eg Whiteline makes bushes to replace all the OEM bushes except the compression arm bush. SPL makes solid bushes for all the OEM pick up points and so does Superpro who even make eccentric bushes to give you fixed maximum increase in caster, camber or toe where applicable. In my next post i will suggest scenarios to cheaply replace your worn bushes cheaply and depending on the usage of your car eg track day, budget and if lowered etc. I have been in touch with Superpro UK and they will be happy to offer a 10% discount to any forum members who get the bushes from them but i will direct them to the mods if they want to register as traders here and take it from there or just want to offer a discount code for the forum only. Note: i have no financial affiliation with them or any company for that matter as i go along this thread. i just want to share my experiences and simplify decision making for those with less experience but also provide a place for all suspesion related discussions to take place for the benefit of all members here. I will be getting most of my stuff from the US to save on costs and maybe offering an complete import service to get parts (used/new) from the states particularly from my 350z private sellers or vendors. I am still sorting out a few things and of course will have to register as a member trader to start this.

Very nice

Who is still in and who out?! Looks like interest has waned and we are I month away

Thanks Beau for the pics but what i need is the rack dimensions as there are 2; 50mm and 52mm. There are 3 bushes to replace. The 2 "ears" on the right of the pic and the single large bush over the rack on the left. So pleae measure the diameter of both the single and ear bushes and the circumference of the rack and one of these should match 50 or 52mm Cheers

I've seen 167 in Germany so i believe 175 is achievable But in any case top speed counts for nought. I will trade that off for acceleration with better FD ratios

Sure mate, Ill get some pics and dimension up for you tomorrow. As for taking out the steering rack, at first it was quite difficult as its very had to get a 17mm socket as there are loads of obstacles in the way but you just have to find the right combination. Also make sure you spray a bit of WD40 the day before as these nuts are torqued quite a lot. I used a Long strong arm and a 17mm impact socket half inch. I removed the A frame at the bottom of the car to gain some space. I you need some help PM me! Oh and I still have the old steering steering rack, also the bushes on that are still like new considering the cat had did only 25,000 miles before the accident.... Beau Thanks Beau I have been spraying all the nuts and bolts underneath the car for the last 2weeks as I will be taking off all the control arms soon to swap urethane/solid bushes! so it should pay off I am confused about the A frame you mentioned?! Is it the black plastic over the K-member? See link for illustration: http://img.photobucket.com/albums/v208/ ... bottom.jpg

Or try: http://www.archenemy.co.uk I used them and would recommend thier services. They do not have an agent in portsmouth but the nearest agent to you will make the trip. I paid £80 over 1 year ago to roll the rear fenders and the agent travel from oxford to worcester.

Nice job bringing this GT4 back to its full glory Do you still have the dammaged steering rack? Being it a GT4 like mine i would want some dimensions of the bushes as i want to replace mine to urethane jobbies. It will save me taking out my rack just to measure the bushes or getting fake info asual from the stealers who constantly get me the wrong stuff for the GT4. I need the ID and OD for the large bush and the 2 smaller "ear" bushes. How easy is it to take out the rack. what needs to come out?

Sold Lock it up mods

Bump Back up for sale. Buyer pulled out Its version 2 mate. Dave has made 2 variants so far and i had both. Infact i had the 1st ever production nav from him;) The major difference is the 2010 software update and larger 4gb card which i am getting installed before this ships so its as good as new. Save yourself £100.

Not bad for an man with a missing finger and hairy arms I know where to get my next detailing. you or wasso will do fine

Well done cookie to crack this i will get one when i finish all the mechanicals on my zed

I did mine myself and its dead easy. There are to tensioners in the bottom to slacken ad get the belts off and repeat the process. The zed has the ability to auto tension if its slack, must have been pretensioned too tight check and make sure the belt is tracking true on the ribs. Why did you not change both at the sametime Zmanalex may have more trouble shooting ideas but go back to the grease monkey who nstalled it and share your concern

free bump!! Its the best belt and stronger than OEM. Got my replacement fan/aux from you Ian last year. Do you eat belts why do you keep buying them Also simple DIY install for the mechanically savvy PS. Stillen item arrived safely, thanks

the possibilities are ... router filters line reset...or a combo of all 3 good call - check here to see if sky operates LLU in your area http://www.samknows.com/broadband/exchange_search I checked and they do operated LLU in my local exhange I can't wait for cabled BD eg Virgin to get to my area as i hear it is super fast ?correct? Its nice to know i was not the only one suffering with BT and paying exhorbitantly for the privilege

I consider myself a loyal costumer and have been with most services for 10years or more and they have been having a laugh. their speed was no were near quoted (i know..... i know the drill but common........you would think they will do something about it) and i become very fed up with the BS and decide to go to sky. when i called then for my MAC code it was a struggle as they were doing everything to retain me even offered £5 pcm for my full package unlimited down low and they will come a trouble shoot my lines to get more speed etc etc. So i told them to fark off as i had made up my mind especuially as i have Sky world and was taking their unlimited phone and broad band which worked out cheaper than BT anyway. The modem came in ontime and today i installed it within 5mins and it works without issues and faster than BT by far. So what's the catch? if SKY s using BT lines why am i seeing faster speeds I think BT is just complacent and are just plauin lazy to keep up with the times and i am glad i took this decision. Next..........is British gas who have enjoyed keeping my acounts in credit for years making interest over off it and when it came to get a new boiler tried to reap me off on the price off the boiler and the installation fee. After that i will deal with L&G home insurance/building and contents Next!!!!!!

PFFFFFttttttttttttt Overated and overpriced the lot. no doubt good quality so sad to here of their demise It was their own bloody fault

Looks good Stumpy G Did you by any chance amire my LEDs prompting your purchase Its a nice mod so now complete it with the 80 or 100w H7 high beam buld to match the whitenes and bluish tinge and get so silvertec repeater to get rid off the orange OEM lights. Careful not to chop off the rest of the fingers Meant to call you after a last meet but been busy Thanks for the open invite and meeting your lovely family. I will surely get that same brand 3D TV....its stunning see you when i'm next up you neck of the woods and hopefully the zed is sorted for the promised hoon
