i looked at these as well, but if you speak to adam at Z1 he'll tell you what he thinks, apparently they crack really easily hence they are replacing them free of charge. its plastic and a very rough outer surface. and adam reckons they don't make any gains compared to a spacer. where as this should make the gains as its a spacer built into a plenum. and its CF so shouldn't crack like the plastic good note, dont know much about them to be honest since im looking at the ssv at the mo. (sorry for thread trashing)

3rd dibs.... auction?

But thats not in carbon fibre suppose that's true

Not trying to be smart here or a party pooper but a plenum spacer / plenum in carbon might be a cool idea but 250£ would get you a kinetix plenum (http://www.kinetixracing.com/kinetixrac ... 03-06.aspx) with a life time warranty. (90$) shipping. Just saw they got a 25% deal on the SSV plenum so that's what I'm going with

Great fun for sliding about though I slide enough with my tiny rear tyres! 235! Strange though that its all a bit of 'fell' and 'myth' regarding tyre pressure which is SO important!?!

Hmm, not sure I'd agree with that. My Falkens say 50PSI max, and when I was at an airfield day, I ran them at 45PSI. These felt far too over inflated and reduced grip massively - which was the intention of doing it on the day so you lose grip earlier and slides are more predictable. I would start at 35PSI and work a bit higher and lower. When you track your bike, I assume you take warm pressure readings too? In which case they are close to the OEM 36/34PSI due to the heat? they would rise with about 3-4 PSI, to land somewhere around 31/32 front and 30ish rear. (it depends on how heavy I brake on the front side), its terrible how much 'feel' goes into this though. The lads that really know use lots of strange formulas and feel to get it right... the problem I have is that I'm having a hard time finding the right pressure for me... Agreed that 45PSI sounds far to high...

some states 10% of max pressure is a good starting point. tried finding something on the net on this how to calc the correct pressure depending on tyre-wheel and weight of car. (normal driving) Since I do a bit of track on the bike I know how important it is with the pressure so normally I should run 36psi front and 34psi rear (according to the book) on track I run 28 front and 26 rear... Its a bit of strange one that there isnt a straight enough answer. I found looking around that 10% of maximum pressure seems to be a good starting point and then you can "feel" the way the cars handles etc when you have that and adjust accordingly.

Ok keep it here instead What size thickness is the 5/16 plenum? I'm sure it's similar to mine... (pure plenum) I could give the quality a go if you wish? (test it on DYNO and run the car pretty hard) for a reduction in cost.... this would be pretty sweet!

Hey mate, I agree with you... did actually snap one in the middle...scary stuff, very easy to do though. This mold you are creating will it need the spacers in the middle or will they go all the way down to the top ?

very true, but easier to replace a bolt then a full plenum...

Sorry just getting confused now... who is making molding what from where and to what price?

really if you go through all that bother would it not be better with something like this:

i'd say it could crack if you over torque it , anyway some photos would be cool!

the problem might be that you need to extend the 'pipes' on top (where the 6 bolts go) in the spacer kit you use the white washers/spacers for that. Also whoever wanted to get this would need to get separate washers/spacers for the strutbar and also longer bolts.

Can take more photos and possibly give a mould of the spacer, not sure re the plenum (id say someone on here will have one 'spare')

can you do a carbon plenum using my pure plenum spacer as an additional for the mold so I dont need it on the car?

hmm that sounds VERY interesting... group buy? Who's doing it for you?

hmm not that long my tuner blamed my fueling problems so had to take it out again. 3-4 months, 200 miles per week maybe, it does not really get 'stressed' under use, no moving parts etc. Might put it back on.

wsure they are pretty much the same really :bye:

you'll upset BM if they do bm like the stuff !

Thats really good - Im impressed with that. Ive just seen this of a mate in the states new setup ............. no image...

Found this one on ztech thats pretty good and should cover any Q's? http://www.350z-tech.com/zwiki/Tires_(FAQ)

Welcome! you make carbon wheels?
