LSD, Traction bars and Suspension.....I have some Tokico blues if your interested. I can take you for a ride in my car and show you how traction bars and an LSD help (in 2nd @ 7k).....but I would honestly suggest that. I have OEM suspension and run some shitty times, but I also launch like a pussy cause I dont wanna break anything. Here's a check list
LSD (I suggest Quaife)
Traction Bars ( I have Lakewood and they work great)
Suspension (preference...up to you)
275 HP axels (with LSD take your WHP devide it by 2 and that is the HP axels you need, w/o LSD use the total WHP)
Hope this helps
