SPC Camber bolts.
|
What P/N and what page is the Camber Bolt on you are referring to?
|
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... http://www.spcalignment.com/componen...AFrom&to=USATo |

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 |

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 running 36 front (cold) and 40 rear (cold)
dunlop sp sport maxx tt 225/255 I will do the test with more pressure, more front pressure = more understeer |

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 :smash:). 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 :y Just put the two washer between the strut and hub! |
Great, ill do the washer mod first then a 19mm H&R rear sway bar. Thanks a lot man!

That will make the biggest difference. |
That's I think, but read this articles:

If didn't fade they are good :y my z2 overheat in the third run, also in lapping (10 min session)
Dunlop in 285/30r18 or rival in 255 are a good option I will check that! |
