Thanks for all the extra info, I'm planning on putting 147 GTA ARB on the front of my car to replace the failing standard one.
What sort of affect can I expect leaving the rear standard? Or should I be looking to change the rear one at the same time?
Thanks.
P.S. Values I posted in second post were given by someone on another forum
