Drag Tyre Profile

[exXU1]

I put this in thr drift n drag section with no results , any one have a valid oppinion?

GTR in  a drag strip scenario, 15" rims , high wall micky tompson slicks on rear. SMALLER WALL PROFILE  on 15' rims also with MT on front.

Bieng that it is a straight run and hope fully with slicks on back that there should not be too much wheel spin at the front , what could be the outcome .Will it hurt any thing?

For i see that the attessa  should not activate if the back is not spinning, particularly down the majority  the strip , but rather a tweak in gear changes?

You thoughts and experience please. <_<

ATTESSA is load sensative also not just slip and only very minor rolling radius differance is advisable, HKS contoller may help but would take some working out.Many GTRs run a hand lever style much like a Hydraulic hand brake removing the ATTESA system in Drag only applications but still not sure it would help as world wide ppl have used the same tyres front and rear so info is going to be hard to find.

Same diameter tyres front and rear is essential. (width is irrelevant)

Think of the ATEESA system like it's a clutch ('cause that's exactly what it really is).

By having different diameter tyres front and rear you are askling "the clutch" to slip all the way down the strip.

All the while the ATTESA ECU is trying to stop the clutch from slipping with additional hyrdraulic action.

Obviously this is not a good idea.
