Stutopia 158 Report post Posted April 15, 2017 Could someone who's either fitted a kit, or individually replaced the engine bay bolts, advise the list of sizes? I've done a fair amount of googling and can find various kits, but no bolt list. Share this post Link to post Share on other sites
Stutopia 158 Report post Posted April 25, 2017 After messing about taking bolts out, measuring, putting them back, I have a list of sizes to dress up the engine bay. In case anyone else is looking for the info: Bolt A - Wings & Bumper 23x M6 countersunk bolts, 15mm length 23x M6 countersunk washers, 19mm o/d Bolt B - Slam Panel 2x M8 countersunk bolts, 20mm length 2x M8 countersunk washers, 25mm o/d Bolt C - Airbox and Noise Maker 2x M6 countersunk bolts, 35mm length 2x M6 countersunk washers, 19mm o/d Bolt D - Bonnet & ABS Unit 6x M8 flanged hex, 20mm 4x M8 flat washers That will give you most of the OEM bolts around edges of the engine bay, plus the bonnet. I've not changed the ones on the pulley covers, or throttle body as I'm replacing these separately with something aftermarket, so they're not included in this list. Neither are the ones for the strut braces or the suspension, they're in good nick on my BRZ. I may do some more in future, I'll add any further specs as I find out. For reference to off the shelf kits, you can put this lot together for about £85 from pro-bolt. Though this list is not quite as long as some aftermarket kits. Some Of The Bolt Locations This is all for info only, don't replace strong steel fittings with soft ally or cheapo items, stay safe 5 1 nerdstrike, ThatGuyThere, wilki and 3 others reacted to this Share this post Link to post Share on other sites

nerdstrike 186 Report post Posted April 26, 2017 Now I think about it, those hex key fittings look like they could turn into a problem after six years of corrosion. You're in trouble if they round out. Share this post Link to post Share on other sites
Stutopia 158 Report post Posted April 26, 2017 I ran the same ones on my Zed for 4 years and they didn't corrode, so I'm not too worried about this lot. 1 Sideways? reacted to this Share this post Link to post Share on other sites
