hay I seen your car its yellow it's looks likes you are getting ready to paint it is that the one mate

Softer springs front will not help with traction in a rearwheel drive car.
It will make the car unstable at high speed and when braking hard at the end of a run.

As mentioned, trial and error is the only way you will find out what works and what not.
Try the tramp bars and see what happens, but I don't think it will reduce wheelspin.
Only suggestions I have is the following:
1. 225 semi-slicks 15's at rear.
2. Spin them up at the beginning of each
run to warm up.
3. Just before the run put some track bite
and a quick spin over it to increase
traction a little bit more.
4. Tyre preasure you can also play with.

See what happens. Hope the diff hold up.

sorry i lost your number onmy old phone
sms it to me
there a big race in durban in two week an d one in jhb in 3 weeks
we want to do the both hopefully will see u there in jhb and abt the tank it cut down so that would not help
thanks

will installing softer springs at the front help with weight transfere
what do u guys think

@Minnesh
I already have your number.Gave you a call once in the past.
Will contact you after 8 tonight on free airtime.
Something else. What about modifying the position of the fuel tank to be more towards the back of the car. Will shift weight more to the back wheels to increase downwards weight.If you know what I mean. To be honest, trial and error is the only way you will be able to determine what works and what not. When are you guys coming to Bloemfontein for a drag race event? Would love to meet.Can organize everything for you.Guesthouse for cheap, etc.

thank u
how do measure the pinion angle
what vis nthe best pinion angle for max traction
can u please assist with this advise
many thanks

extending the rear shackle mounts does 2 things:
1) raises the ride height
2) changes the diff pinion angle

the latter can alter the way the car puts power down. But it is better done with wedges fitted between the diff and springs. You will need an expert to measure the diff pinion angle to determine if you need to alter it. Remember also that under power the diff pinion angle will change - it will rotate upward at the front of the pinion due to torque reaction - how far depends on your springs and anything else you have on the back. one of the things that 4links and tramp rods do is help to minimise dynamic changes in pinion angle.

hi are u well
yes never ever worked on the wheelspin,now have got some bf goodrich to try on but want to fit a 4 link
thanks

Oh ok. You just gave the answer to my question.

Only way to increase traction is to fit stickier and wider tyres.
Suspention can only do up to a point.
