Xb GT axel hop

[rhettwalker1985]

G'day,
The drag season is starting next week and I have finally fitted the new extractors and car by spacer, can't wait to take my coupe back down the drags to improve on that 12.4 time.
The car is a standard stroke 51 clevo with 185cc 3V heads, c4 with 3000stall and obligatory 9 inch with 4.11's, pedders shocks all round and new bushes and rubbers (neoprene) all round. The car drives like it's on rails and handles extremely well for any car let alone an xb! I do not want to sacrifice the handling of the car as it is almost a daily driver and drives awesome.
The rear tyres are 275 x 60 x 15
The car runs pretty consistent 12.4s however I have to give it almost no throttle off the line or it will spin and then feed it in as I go into second.
I refuse to use slicks as I want to do a time as close to as I can on the street, with all the same gear on the car.

The car has issues putting the power down to the ground and axel hops like mad if you give it too much. Just feels as though the rear end is trying to lift up rather than be pushed down.

I rang wilkinson suspension as they are very close to me, they asked straight away if it was a GT. I said nah and why, they explained the genuine gt's had a traction bar or spring helper thing that fixed the problem and can do to my car for only a couple hundred bucks.

Anyone know more about these??
