    Howdy all,

    I keep hearing conflicting information on the use of coilovers in SP -- the rules seem to say they're permitted (14.5 C, 14.8 A), but...

    I'll leave this question open ended in the interest of discussion.

    I always wondered if the SCCA had a "Maybe Committee". It sure seems that way when you read the rulebook.I've got the same doubts about an adjustible rear spring on my B\SP 'Vette. If you read the Rules enough times it might be 1.Legal or 2.Not Legal.Maybe!!!

    If you read in 14.8 A it states "must use original spring attachment points". On my car the spring attatchment points are the a- arms, not the shock, but on some cars it is the shock. I think that this is an unfair rule because if I had a car with shock mounted springs originally, then I can use any shock/spring combination available, which would give me a distinct advantage over others who are restricted by this rule.

    My interpretation,

    Britt

    As kiva75 noted, you must utilize the factory (original) attachment (mounting) points. Having a Honda, this rule works [b]for[/b] me. If only I had $2,500 for a race quality threaded shock body set-up SCCAForums Image.

    kiva75: I think I remember seeing your Cosworth Vega at the Bremerton NT last season. Didn't get to see it run though.

    As long as the shock attachment points aren't changed, I believe you can run Coilovers. I guess all the cars I have modified have a design type where the spring is mounted to the shock. I good answer may be the BSP Vettes... Have they done this... if not, then I would say it is not legal.
    Matter of fact, Now that I think about it, Guy Ankeny in a C4 Corvette was testing a carbon fiber tranverse spring, so I would have to say it isn't legal, because you can easily retro fit the Vette's for Coil Overs, but you would have to remove the Factory Spring Mounting Location.
    Sorry!

    Okay then, somewhat less of a black and white matter. I'm glad I'm not going crazy. SCCAForums Image

    In my case, I've got Mac Pherson struts, so essentially using the same thing with an adjustable height perch should be okay, or at least jive with what everyone's saying.

    For the back, it looks like changing the arrangement's not okay, but putting on a spring perch that's height adjustable should work.

    Thanks all!
