    Default LR Spacer?

    I see more and more people running them, whats the effect?

    I know its been stated on here many times, just didn't find it today.

    Also, adding one to the LF, would that make a car steer in on entry a little better?

    Thanks, Krom

    Merry Christmas all in the Tech Section as well !

    I honestly believe it mostly got started because Rocket had a lot of orange car rears to sell when it was a flop. They had a shorter lr axle tube.

    On the rare occasion I got to race at the old Lawrenceburg, IN 1/4 mile (RIP) I used to run one on the LF. I felt it helped the car rotate. It might have been in my head.

    I would think the LR would take weight off the LR, looser exit, more RR drive. ?

    I notice on a lot of Bloomquist chassis that he uses a lot of spacers, LR, RR, and RF.

    I plan on tinkering with these a little this year, seems like a good way to make small adjustments on the fly.

    Just the opposite. It makes more lr drive, but you have to add the bite back in. The spring feels softer because the tire is farther away.

    Simple explanation:
    LR: tightens whole turn
    RR: loosens whole turn
    LF: loosens entry
    RF: tightens entry

    You get the lr more to the left of the car's CG also. This tightens on throttle.

    True....it was a standard adj on our blue/gray Rocket, but we just left it on at all times.

    We used wheel spacers a lot 30 years ago.

    Why do so many big teams use spacers on the left front? Anywhere from 1/4 to 1" out. Whats the purpose and theory on that?

    Doesn't a great corner start at turn in?

    Lf starts weight transfer at turn in, mainly. Spacers tune how much and timing.

    I have been using a 1/4" one on the LF just to help our car turn in. It seems to help, so i am contemplating a 1" spacers and also adding one to the RR, for early in the night track conditions.

    Thanks for the handy list Jim11h.

    Back in the 80's I used different offset wheels since our rules did not permit spacers...

    I used to use on lf early in night to turn in better, really heavy went to RR. Feature time and track slick would put on lr. This was 2" spacer. Anytime krom. I'll look thru some old setup books and see what else can find.

    It's been 8 or 9 years ago that I observed a ridiculously offset wheel about to me mounted to the LR of the zero car. He was standing right there and I commented or asked (can't remember) on the wheel offset and he said it was two inches. I had never seen one before that and haven't seen one since.
    This was just before a feature on a completely black slick, blown off track.

    Matt I thought that was the start of the sweet bloomquist cars when he had the two off stuff? Thought he was shortening the tubes and running more offset.
