I want to hit a sub 5 sec 0-60 at trax this sunday. Last year i managed a 5.36 at the FCS at Bruntingthorpe. Since then I've saved more weight and have adjustable suspension (raise / stiffen the rear).
The 5.36 run was done on shagged out yokohama a539's that have gone very hard, I still have the yoko's but am unsure on the following, do I
A) get some tyre softener and treat them b4 the weekend
or
B) buy a pair of Toyo R888's?
Any advice or people with experience appreciated.
