Splinter has a set installed to provide extra camber up front.
I've got a set sitting in my garage waiting for install, but I'm still on the fence about if I need more camber or not though...

Hi, I had tested this bolt but they are good just for positive camber.
What camber numbers you running for the track? I have a stock suspension on my c55 + washer mod (1) + camber bolt. I was running -2.8 right, -2.5 left, stock rear about -1.5 and -1.6. But it’s hard on front tires. I think that I will put more washers with longer bolt for more neg. camber. I think I need about -3.5, -4 for the front. I know it’s higher for street but … Supercar v8 race car running about -5.5 fronts and -2 rears
How many washer you had tested?
Thanks

If you need that much negative camber, you need more air pressure in your tires because they are just rolling. I am running 1.75 up front and they are just rolling to the edge and wearing evenly. Most of the all out track cars running on street tires won't exceed 2.5 degrees.

I run 36 psi front, 32 rear and have a hard time keeping traction with 1.75 degrees of camber up front. Also, strip out the spare tire and all the crap out of the trunk when you run.

Did any of you guys end up picking up the SPC camber bolts? Any updated experiences? I am looking to kill some of that understeer with either the washer mod/ spc camber bolts/ or the 22mm Eibach rear sway bar.

Last year setup:
Tire 225/255 dunlop sp sport
Camber: front 2.5 (camber bolt + washer mod), rear stock
Sway bar: front 23mm (stock) rear 22mm eibach
No LSD
Brake: ebc yellow
For autox: big change for auto x and very predicable.
At the track: the car feels with a bit more of over steer but not a dramaticallychange (No LSD)
This year setup
Tire New Dunlop S.S. Z2 255/40r17 all around offset 30mm
Camber: front 2.5 and rear stock
Quaife LSD
Sway bar: front 24mm eibach, rear22mm eibach
C63 rear spring 25% stiffer then c55 rear spring
At de track:
the car feels very fast, just a bit of under steer inlong turn (oval style) also the braking with front 255 tires is amazing.
I have a video in lapping:
For autox :
I have too much of over steer (real drift car
). I will try the 19mmH&R rear sway bar.

With a 19mm rear swaybar, the car are very fast in autoX.
I have a good setup for autocross, but next year I will try 285/30r18 tires to the rear. I will keep the 255/40r17 to the front.
my best run last week-end:
I had the third time overall (not indexed)

Good stuff, I'm thinking I will start with these SPC Camber bolts and maybe a 19mm sway bar for the rear. I just want something that will corner better on the streets with less understeer and no noticeable tire detriment.
Thanks for the setups and vids!

SPC Camber bolts not work for neg camber, you need eom camber bolts.
But the best way are washer mod, it's free
Just put the two washer between the strut and hub!

Get the last Grassrootsmotorsport Mag, they tested them, yes the Direzza was marginally quicker for an expert driver but the BFG was more consistent and didn't fade.
