    What should I do for my autocross setup this year?

    Hi, I just recently found this forum. I hope you can help me with my dilemma. I have been autocrossing for 10+ years and I recently moved from a highly prepared Miata to a highly volatile e46 M3 Convertible. Mainly because I needed the back seats for the new kids and I enjoy racing with the top down too much to get a coupe, so this as the best compromise with my SO...

    I have driven the e46 M3 Vert for two seasons now. The first year I drove it completely stock, that was a huge change from my Miata... Last year I added UUC swaybars and that tamed the side to side lateral body roll a lot.

    This season I am going to move up one class in my clubs points based system.

    I miss my double adjustable dampers that I had on my Miata. My M3 bucks and dives way too much on acceleration and braking and I think a good set of DA dampers can help control that and help me speed up the weight transfer of this beast.

    The problem is that with my clubs points system I only have enough room to add either Shocks and Springs without Camber Plates OR Shocks and Camber Plates with OEM Springs...

    I cannot add all three or it pushes my car up two classes, and I don't want to do that.

    So the question comes down to which would be better for autocross with my DA dampers with Stiffer aftermarket Springs or Camber Plates?

    The surface we race on is pretty smooth concrete.

    Can I get enough camber in front from lowering the car down an inch all around to 13.5F/13.0R with aftermarket springs?

    Can I get enough camber with OEM springs and aftermarket (probably Volshlag) camber plates?

    Thank you!

    Lowering doesn't buy you much.

    You can, however, swap the strut hat's left to right (and give them both a 60 degree turn). There used to be a DIY, but it is gone now. They will only fit in one way to give more camber. Technically still stock, but it will NOT be at stock settings (do your club rules specify stock equipment, or stock settings?). That can give you a degree or more camber.

    Also Madrussian has some good DIY.

    Another Camber adjustment

    If you are allowed to stay stock on parts, and make adjustments outside of stock range without it counting against you in the rule book, then this might allow you to get adjustable shocks and new springs.

    The rules specify stock settings

    Thanks for you input. My club treats swapping strut hats the same as camber plates.

    I have pulled the pins, that is allowed, but I only got -1.0...

    How much camber can I get with the stock springs and camber plates?

    Question...

    Are spring/shock combinations differentiated from suspension with adjustable perches (coilovers)?

    I would much rather have a good suspension and not enough camber than more camber with stock springs.
