Hardrace Suspension Upgrades for G20
These are available for the G20, and for good value too. Did a bit of research on them and they're supposedly pretty good quality. Interesting note is that it is also made compatible with the A90 Supra. Wonder how these mods when installed on G20 will impact ride quality.

Why do you need more rear camber? Factory spec is -1.67 to 1.75deg (+/- 0.42deg) in the rear for the various G20 suspensions. That's more than I run for the track on my F31.
The front is typically where BMWs need more camber with the macpherson strut design. With the multilink rear, the negative camber increases as the suspension loads, versus the opposite of losing negative camber with the front macpherson strut. Now if you're just looking to make things stiffer by removing the rubber bushings in the control arms and replacing them with monoballs, these arms would work for that.

I am currently looking for front suspension parts too and I think SPL has them made for the A90 Supra and the G29 Z4, which means they should fit for the G20 even though it isn't listed, we share the same suspension. Just looking for parts as I am on lowered suspension, and these seem to benefit the springs. I'm not looking to do coilovers anytime soon so small upgrades to the stock suspension is what I'm looking for at the moment. Besides the functionality aspect I'm just looking at more rear camber adjustment for aesthetic purposes, though I agree the front honestly needs more for high speed turning/cornering. |

I also want to know, if for instance I run SPL front lower control arms and I run the rear Hardrace camber kit, will that be fine? Or should I be running the same brand suspension upgrades for front and rear? Just wondering because if I end up going for the Hardrace camber kit whether or not I can still go for another company for aftermarket for the fronts.

See my video below at 3:50 why you might want adjustable end links. More rear camber with as little as BMW provides up front will just make the car understeer more. That's actually the reason BMW specs so much rear camber stock from the factory, so that you understeer instead of oversteer. Quote:

Swapped out my winters for my all season performance tires back on today and honestly they perform so much better than my winters, it's actually a day and night difference. Handles quite well now, actually. Anyhow, I'll take a look into adjustable end links, sounds like an upgrade that is actually worth the money for some decent improvement in handling on a lowered car. If I do end up doing SPL front control arms or the Hardrace camber kit, I'll be sure to keep y'all updated! |

Hey guys made an account to comment here - I bought SPL lower control arms for the A90 supra about 6 months ago, tried to fit and they wouldn't, this was with RBM Hampshire, BMW specialists. Turner just released LCAs designed for G20. Will be buying them in about a month

"This product is no longer available for purchase." I was looking at these a few months ago & wish I had bought them.
