i

The program is "Rhino 3D ver3.0"
im about 90% sure how diffusers work
the ratio of inlet to outlet is still to be decided
im still redesigning the rear floor pan and a retub of the rear wells At the moment

if you know of any good sites on diffusers id like to see them

other than that its still a pipe dream

If only I could turn the clock back to 19 :lol: and make some smarter choices where to spend my money!

Torque steer to me is the deviation of the car from the straight ahead without turning the steering wheel. Just cause a car wants to turn under power and you have to fight it doesn't make it 'torque steer'. My car turns left under power and right with the power off with me holding the wheel in the same position - that's torque steer and its scary. Coming onto the straight at Wakefield say - I point the car roughly where I want to end up, floor it and see what happens...

Also I know the difference between stock, serious power and stupid power - an LSD seems to make little difference but compliance in the suspension bushes certainly does, so do bumps.

All I can say is good luck

Daniel
