thanks for the replies guys and your message BK. im urnning the m3's on the front just because i figured they would wear less there and have good grip. the m2's worked pretty well on the back. i have a pair of m3's for the back to try also.
the car was understeering a bit at first but that was with stock front tyres. with the m3's it was alot better. i just want to make it a bit more planted. its still a little loose in the back and can come unstuck occasionally in corners and under power. im running the stock foams and shock oils.
when you guys mention shock limiters, you mean inside the shock to prevent droop right?

i raced last week and it was great compared to the rest of the field. i came 2nd, however the truck that won was a well setup box stock slash!!! i own a slash too so i dont know how he does it other then being an amazing driver, i just wanna get mine a bit more dialed to catch him with my 'reduced' skill level ie i dont have 25 years experience!
