Get somemthing OTS that can be revalved later down the line. You can do all the calculations and obsess over it before even testing, or get the ball rolling asap.

I myself spend countless hours devising what I would think make an existing 2 way shock work. Did all the work and then some. Threw them on the dyno.. Turns out the compression adjustment dont add anything but extra hysterisis... Wasted time and energy that I could have just avoided had I not been so obsessive about details.

Edit:
Rebound adjuster.. not bad not as digressive as I would have liked

"Compression adjuster" response...

Hmm.. the pictures are not showing?

Cut out all the metal from the doors, tomei since it's the lightest, carbon roof, carbon trunk, mph fab hood, essex sprint bbk, "swiss-cheesed" where applicable

Need an advice about further suspension spec. What we've got now is 2013 brz on stock shocks and Eibach sportline springs +camber bolts on front(-2 camber atm). This car is mainly used for track days and i don't care about ride comfort, only performance matters

There're still a lot of things to be done with the car for track days besides the suspension so the question is should i go for some kind of coilovers like BC racing DS series or they aren't worth it and it's better to buy new B6 for my Eibach springs and save money for other mods?

Alarik: more, more, MORE camber, if for track. Move up to -3 to -4 in front, depending on tires/track.

Easier said than done, it's almost max camber with this spec. That's one of the reasons for BC's coz i'll get camber adjustments

churchx · 10-04-2020, 05:07 PM

You can add front camber with stock shocks if you add eg. pedders eccentric rubber topmounts and/or powerflex front lca rear bushing on top of camberbolts. Or camberplates.

If you want to read about weight loss you should have a read of this thread.
His second post in the thread details all the weight savings.

What other options do you have?

What kind of tires do you use?

atm only spec that i described +intake, if it matters. But i got plans to reduce weight a bit, headers+exhaust and dyno tune. Wheels 7.5J, tires Federal RS-RR\Rs-Pro, Hankook RS4 215 or 225 width, depends on local series regulations.

Racecomp Engineering · 10-05-2020, 11:22 AM

Sorry I meant what other choices for suspension do you have? KW maybe?

Oh, my bad

KW, ST, Eibach, Bilstein and Tein can be bought here, i guess. Something else will require shipping from US +taxes.

Racecomp Engineering · 10-05-2020, 11:45 AM

Most of those (including Tein) are much better than BC. We like KW and Bilstein a lot but they don't always come with camber plates.
