SCCA Solo C Street Discussion

[bslate3]

That is insane that people are getting 1.9 with Koni shocks and TRD springs!

I got a massive 1.0 on my BRZ with just camber bolts and pushing in as best as I could. I need more front negative camber.

Can you get more negative camber with the Bilsteins too?

If you can get more camber with one type of strut over another, it is illegal for street class. Apparently you can get more than stock with Koni full replacements and the camber bolts, but it won't fly in C Street.

Sounds like people are pulling 1.9 degrees with TRD springs and stock struts.

It's not insane, there is a camber curve with the front end, as the suspension compresses, it will gain negative camber to an extent. So by lowering the car with the springs, without anything else, it is quite possible to gain a half a degree of camber at static ride height. A double wishbone suspension will gain more than a strut suspension. My EF honda gained 2.5 degrees when I put koni's and GC springs on it. I think I dropped it about 1.5" or so, but that was an STS car.

I was at 1.5 degrees, crash bolts, loosened top hat, jack under hub applying pressure, tightened everything.

Manufacturing tolerances. Hell, that's the whole reason why camber bolts exist in the first place.

Can someone explain to me how the Koni strut is illegal if it fits within OEM manufacturing tolerances?

Can someone explain why some of you want to ban a part that makes your life considerably easier than if you had to install inserts?

Does anyone want to guess who a protest committee is likely to believe more: you stating the part is illegal, or Koni (with their excellent reputation in the community) stating the part is a direct OEM replacement? Do you have a plan to prove Koni wrong?

Hopefully we can put this to bed and work on finding a way to beat the MX-5s and the RX-8s with the cheater engine rebuilds. Now there is a juicy protest candidate if someone can find out what secret sauce is going into the blender...

Yup. Not all strut suspensions have a camber curve (my old Celica didn't) but we got lucky.

How much camber you gain under compression varies from car to car because of, once again, manufacturing tolerances. You're going to have a very hard time throwing paper at someone because their wheel looks more bent than everyone else. "That's illegal because I don't think it's possible" is a good way to burn $100.

If you like watching that much money disappear instantly, I recommend instead that you bring a keg to nationals.

What are you TRD suspension adopters using for a front sway bar?
I know of one person using a Hotchkis.

I did the TRD bars front and rear. Front is a 21mm and the rear is a 16mm. Car feels really good, with a tad bit of oversteer, nothing like the other option springs and bars where it felt like it wanted to snap all the time.

Trd front and rear sway bar for me

[scirocco78]

I'm running the Strano bar with Koni's and have the car dialed in where I love it. I'm trying to figure what's going to happen if I buy the TRD springs and just run the rear TRD bar.

So if I can get -1.2 with bolts, buy replacement shocks and go to -2.2 that is now fine? If -2.2ish is now within "tolerances " then I'll just slot my OEM shocks which NO WAY in hell get that camber. Why should I be screwed with tire wear because Koni decided to do this?

I've done three events with a stiff set Hotchkis. Switched it to the soft setting after the last event, as I decided that as awesome as the car is in transition, sweepers were too painful. Have yet to try it...

No one says you have to crank it all the way over. Besides, you're in a BRZ, you probably won't get 2.2 degrees as you're sitting an inch higher.
