Default 05STi STU setup question Rear Camber Plates or Rear control arms/links??

Hey,

I need some help deciding what to run in the rear of my 05STi for STU and possibly ESP/BSP in the future. The way I understand the camber kit rule in ST you can have either camber plates or adjustable/different control arms. For the front obvisously I went the camber plates as they are neccessary to get the desired camber and be able to adjust the car from street to race settings with ease. But in the rear I am trying to decide between cusco or other camber plates vs group n tops and different lower control arms. Is there any benefit to getting different lower control arms/links for an 05 STi? The struts I am getting are slotted in the rear for camber adjustment does this prevent me from legally going with different lower control arms/links?

Basically I am just trying to figure out what is the best setup and order either rear camber plates or group n tops now and other bits later if i can legally do so.

i can't answer that. but I am curious as to why you would want any additional camber in the rear over that which the stock geometry already allows for?

I'm not a big fan of using the arms to control camber. They are very nice for being able to change toe though. The reason for changing from the factory is to at least get the same camber on both sides, many cars end up being very different from side to side.

Double check the rules on the lower control arms as I am not sure they are allowed in SP. Could be wrong though.....

Thanks for the help but i still don't know if they are legal with slotted struts. I do that if i used non factory camber bolts, camber plates or offset bushings in the rear then I could not do the lower arms but nothing about the struts being slotted.

Anybody know of slotted struts prevent legally running different lower arms?

You are right the lower arms are not legal in SP. But camber plates and bolts are legal. So if there is no significant benefit to running different lower arms in ST i will just order the camber plates and be done with it and be legal for SP if i decide to go there eventually.

You can also always slot the struts in the back as well. Those are legal in any non stock class.

and Tom REALLY knows the rules !

DougM ... you might want to add more rear negative camber to help balance the car as you develop more grip in the front. If you are suffering from Snap Oversteer ... adding neg. rear camber usually takes care of that.

With my SM Wagon ... with the addition of sedan A arms, lots of neg. camber and positive caster, R tires, etc. ... I now have enough grip in front that I'm up to 2+ degrees of negative camber in the rear. A more talented driver might be able to control the added oversteer and choose not to have as much neg. camber in the rear.

I like my inexpensive Whiteline Adjustable Lateral Links ... because it's so easy to make changes ... but ... you can change Thrust, Toe and Camber all at once ... with one change ... so you have to be careful!

Changing camber with rear camber plates can be a real pain in a sedan!
