I've a front wheel drive Nova which I race in grasstrack. Engine/power wise its strong but handling could be better, basically it turns in real well but on the exit of bends it pushes on horribly (remember we race on a loose surface) basically I have adjustable damping on the front and can change spring rates on the front, adjustable damping and platforms on the rear and I can work with tyre pressures/tracking etc but thats all the adjustment I have, I'm not asking for settings etc but just want suggestions on where to start making changes to improve things a bit, I don't mind compromising a bit of turn in to help things a bit...can anyone help me out

Hi, From experience rallying FWD I would look to reduce front spring rates and soften front damping. If you have separate compression and rebound its the rebound that needs softening.

If the car already turns in well that would suggest that the front camber is sufficient. Not too much?

Don't forget that fiddling with your back end can help the front 2 .

We just booked a track and done a days testing took note of original settings then adjusted things to make it better once driver was happy the car was better and nope driveable, we just fooked about to see what would do what .

Adjust one thing at a time and take loads of notes and play about.

Also what diff you got in the car if lsd maybe it needs settings played with to make it more suitable.

Or if you've got a bias pedal box set it more to the rear and left foot brake , i have seen that used to great effect to set the back out on a fwd car.

What class is your grasser?

Thanks for all the suggestions, its a class 2 Richard. I did wonder if it could be caused by the rear end, its set quite high as seems fashionable in this class in order to transfer weight over the driven wheels for starts etc where its crucial (I bought it like that so I tried it as it was) but I'm finding anything I'm gaining on the starts I'm then losing over the course of a race due to not being able to get on the power coming out of the corners etc.

Not sure about 2's to be perfectly honest. Seems to be a lot of trends and fashions.
I would guess that running high and soft on the front also helps the turn in due to weight transfer when braking at the end of the straight. You just don't want the front to unload that quickly when you put the power back down. What adjustment have you got on your shocks / struts? Have you tried lowering and stiffening up the rear?
The alternative is to get inside someone who doesn't understeer and bounce off them as seems to be the norm in Class 2!

Yeah think I'm gonna start by lowering the back and stiffening it a bit see where we go from there. Cheers
