Can only comment from personal experience - my Exide AGM is still going strong with no obvious compatability issues with electrics or alternator. It tends to last longer when not in use (useful right now) than the standard lead acid battery in my other car. It also looks to have the same specs (see previous post) as the Yuasa you're considering. Just make sure it's dimensions aren't bigger than what other people have reported being able to fit as it was a tight squeeze even after removing bracket/trim parts (if I remember correctly) to get better access to battery compartment.

These look great! I'm on the cusp of buying some to replace my ARK DE Performance R-Spec HFCs that both cracked recently. Anyone have any issues or further positive feedback to share now they've been installed for a bit?

I've just replaced my Bosch S5 in my 05 with an Exide 096 AGM Car Battery 70Ah AGM700 EK700 from Tayna for £108 including delivery and VAT. Brand Exide Range Exide Micro-Hybrid Voltage 12 Volts Technology AGM Capacity (C20) 70 Ah CCA (EN) 760 A Length 278 mm Width 175 mm Height inc. terms 190 mm Guarantee 3 Years The S5 was OK and has lasted 3-4 years (notably less than the original battery). That said it did run flat once over a 2 week holiday in the winter and struggled to hold charge for long thereafter. Given the price, I thought I'd try an AGM battery as they're supposed to hold their charge for longer, especially in colder conditions. Of course, only time will tell, but so far it's been top notch and appears to be operating very comfortably (not surprising given its spec). Like the S5, the Exide AGM was a tight squeeze but fits snugly once installed. Just make sure you remove all the plastic edging held in with the standard poppers and pull all wires out the way before installing as it's pretty heavy.

Hi Matt I used an aluminium bracket from an IKEA spice rack that I was "supposed" to be installing in the kitchen It measures 35mm x 350mm so you might find a ruler would do the trick if you're unable to find/fashion a similar strip. I used one of the existing bracket holes and then just drilled another in it to align with the existing holes on the tray and wheel arches. I installed the bracket so that the softer plastic wheel arch is sandwiched between the rigid bracket and the rigid tray so that the force is spread across the full area of the wheel arch lip, instead of just the bolting points (which are decayed anyway). Here's a photo of it installed - I've circled where you can see the bracket peeking out from under the tray.

Yep, agreed. I've already been on the phone to them -I just have to sort a time to get it in and looked at. Thanks for the comments guys, I keep you posted

I recently had a pair ARK Resonated HFCs fitted to my 350z (2005) along with a new Y-pipe by a reputable exhaust manufacturer. Upon leaving, everything seemed fine and sounded great. However, when I pulled off the motorway and the revs dropped as I went down the slip road, I heard a loud knocking under my feet. The same knocking occurred when going over rumble strips, or any unevenness in the road for that matter. At home, I took a look under the car and realised the driver side cat had been fitted such that the Helmholtz resonator was resting up against the chassis I rang the garage who stated it could be a manufacturer defect as the cats were not made by them. However, they agreed to take a look at the car when I returned from holiday. I'm now back and have gone out in the car again to check the symptoms are still there. When I hit motorway speed there was suddenly a distinctive "whooshing" sound immediately followed by the CEL light coming on. Having checked the code it was a P0420 "Catalyst System efficiency below threshold bank 1" which I understand is the driver side cat in question. Not sure if it's significant, but Torque app tells me that bank 1, O2 sensor 1 is 0.3 whereas bank 2, sensor 1 is double that at 0.6 at idle. I also noticed that at v.low speeds, but when the engine is under load (e.g. uphill, sharp turn in carpark), a couple of times there was a distinctive rattling sound from under the bonnet. I also feel like I've lost some power compared to leaving the garage throughout the range, but I guess this is subjective. My initial searches have got me worried that I could now have a cracked manifold, resulting from the knocking of the cat against the chassis . I'm going to take it back to the garage as soon as possible, but I wanted to put this out there in case anyone has experienced anything similar or has any other advice or ideas about what this could be?

Doh! Sorry to hear that - do you know what you hit? (or rather what rascal hit your nismo bumper! You'll have to get some new pics up when you have the V3 is installed! I've decided to take a new mindset on these things....whenever something breaks, where possible I try to upgrade it, just as you are doing, no matter how small it seems. That way, I can consider my car to be low maintenance as I never need to fix it, I only ever upgrade it! This reminds me, I need to get some new upgrades fitted at your place....PM on it's way

agreed! These look lovely. Put me down for a blue one

I should add that this really is a great piece of kit and very well made - you won't be disappointed if you buy. The fit is perfect and allows for some flexibility. The installation should have been a doddle had I not encountered the following two issues (completely unrelated to the undertray itself): 1. I had a broken bolt head to remove which took hours and ended up with me having 3 broken drill bits and sunburnt legs as they were poking out from underneath the car - to which my missus took great delight in mocking me for. 2. The sides of the undertray attach to the plastic that runs under the wheel arch. Along with my old plastic undertray, the fixing points on this had also degraded such that it was pointless to try bolting the new undertray to. After much head-scratching, I managed to resolve this by drilling a couple of holes into a sturdy strip of aluminium and running this flush along the edge of the plastic to which the sides of the undertray attach. And Bingo - it's now super sturdy!

I took some good pictures whilst the car was up on ramps and I was installing. Unfortunately they perished when I subsequently bricked my phone - doh! However, until somebody posts some decent pics, I can offer the following which I've just popped out onto the driveway to take. It shows the undertray after being installed for a number of weeks....you'll just have to imagine it nice and shiny as it was when first installed!

Undertray arrived this week. Nicely packaged and looks neatly made. Looking forward to fitting it - will post more feedback once it's on! Thanks for keeping me in the loop at all times with regards to its delivery. I suspect I'll be back for some more stuff before long

Just received mine - thanks Adrian. Looks like a neat piece of kit. Looking forward to fitting it soon!

Yes, count me in for one for a 350z. Ta

Doh! And just before I realised my undertray was about to start scraping its face along the floor Any plans to get another order of these in?

Thanks for this guide - just did mine today and it worked a treat (and I can usually manage to stuff most things up). The info is absolutely spot on
