Not sure its worth your while upgrading fronts unless you're tracking it? Thats the advice I got when I changed mine a couple of years ago. Replace the rears & fit a thicker anti roll bar back there too & turn in will improve 100%
what ive done with the P1 was upgrade the arb to 24mm adjustable whiteline
with solid rear cdf droplinks,perrin alk with drop links
am slowly changing all bushing to polypro bushing
i need new ones anyway brian so might as well upgrade them while i'm at it . might look at the arb bars later mabey just change the bushings not really going tracking it
