RB5 Anti Squat

[johnnyboy]

So what's the verdict on how to adjust the anti squat? Shimming the rear arm block won't do it?

Shimming the rear block seemed to be fine for my car

You need to trim the block slightly so that it doesn't come into contact with the motor plate or gear cover.

Otherwise, Jimmy's method of turning the front block upside down helps too - but I found I had to mill the plate slightly for this to work and it still doesn't allow you to run 0 degrees.

I will post some pictures of mine when I get home from work, using both methods you can get 0 degrees without much trouble

I found with changing the rear block only bends the T plate so this doesnt really do anything. The front block does have to be cut down a little and I have it upside down which does drop it a little more.

Thats odd?

Raising the rear block should only bend the rear plate down if you don't remove enough material where the gear cover/motor plate is.

I can raise mine about 2.5mm without hitting and it has no effect on the rear plate.

I have attached a picture of my rear plate.

I just had a good look at mine and shimming the rear block didn't bend my T plate down and I still have a small gap to the motor plate as well so there is no pressure from that.

I've just come back from my first race meeting with the anti-squat mod and wow! what a difference it makes!

On my local track it has transformed the car. My car has gone from fairly quick but very inconsistent to very very quick and much more consistent

One part of our track has always been causing me problems - basically a double jump followed by a 2 tabletops, the latter with a hairpin turn right at the end of it.

Before today, I crashed over this section at least once per race - well today I did 3 heats and 3 Finals without even looking like crashing!

The car was awesome - 3 heat wins and 2 A-Final wins sums up just how good the car was - if only it was this good last month at our state championships.

I would suggest that anybody who is not totally happy with their setup at least give this mod a try.

bender - at 2.5mm, do u know what is the anti-sq degree?
how do i measure the degree?
(if possible, i'd rather raise the rear block than muck around with the front block .. my modification handwork is shocking )

I couldn't tell you exactly how much the anti-squat is as I haven't measured it myself - when I've adjusted mine I kept raising the rear block until it the suspension pin looked flat.

To do the mod you will have to modify the rear plate or the rear block - I don't believe there is enough adjustment by doing just the plate so I'd recommend both.

And if you don't mod the rear block, then when you put shims under it it will hit the motor plate and bend the bottom plate down as Woody has said.
