Thanks, I have the XXX book also. Could be things like Front Springs too soft, not enough toe out in the front, rear springs too hard, not enough rear droop.............

looking for some live advice from V1RR users this time, need a reference point to start with.

Talking about droop. I have ran into a small problem of not able to get enough rear droop with the floating rear end. The rear guide is bottoming out on the turtle. this is not a problem when I run on most tracks, but the local short track has some nasty bumps and the car gets really loose when I find them.

Rear Shocks: top of shock mounting closest to center of car (inner) and bottom in upper mounting hole

Front Shocks are standard

Hmmm, interesting . . . I always thought the MTX-3's looked slightly better coming out of corners.
Are you running a Lola body or Sedan? - same body each time?
Stratus 2.1 on both time, don't forget I run on sprayed track that has twisting the setup a bit, such as a lot of droop F/R.

How is the car bottoming out possible with the rear floating mount? Should not be the case. The rear floating mount prevents the shocks from being compressed when the downforce acts on the body.

Probably on bumpy tracks, you need to increase the ride height a little. I think that sounds more like the solution to your problem.

You actually increase rear droop (say for example +7 to +5) to increase weight transfer to the front... Hence you get more off power steering.

Reducing rear droop makes the off power steering less but you increase rear stability when you apply brakes.

Default rear droop

Try this

1/. limit rear droop to "without droop" in the rear and try it.

2/. set more droop to the rear and run it again on the track, compare the result.

the results on each of the above could be varies due to different driving style, different setupof the car (front diff or front oneway)

weight transfer to front also means you have less traction to the rear. It will be forgiving if you have some droop in the rear but if you have less droop, one of your rear wheels could have been lift (in extreme case) and this cause loose rear end.

In general, the fast moment of weight transfer (front Vs rear) is due to softer suspension setup

Thanks for the help, but after taking a closer look at the car, I am at max droop with the way the REAR pod is made.
If I want any more droop I will have to go to the standard shock tower in the rear.

Driving style and setup of car will dictate the type of rear droop which would benefit the car handling.

A car equipped with a front diff usually requires a lot of steering. Beginners will find it OK but experienced drivers will find it a little lacking. So more weight transfer to the front off power is nice to have. You achieve this by having a lot of rear droop.

With a one way, off power steering is generally more than normal drivers would require and generally, you want to take out off power oversteer in the car. You do it by limiting the rear droop to prevent weight transfer from the rear to the front. Of course too little droop will make the rear end lift up and cause your rear end to loose traction. Too much is always no good. Everything needs to be just enough.
