Stiffen the rear suspension and soften the front one ....
Ive Bilstein coil overs I dont know about yours.
The more weight you keep on the front wheels for (FWD) the more grip you'd have... when you accelerate the weight shifts from front to back which reduces the weight on front wheels and makes it easy to spin.. its 101 gain traction on FWD
on dry roads i normally hook up in 3rd pretty well...there is only an 1/8 mile track around me so idk when Ill get to a 1/4 mile track but eventually. I havent tried to launch from a dig yet as I still have a little ways on the 500 mile break in for my clutch, but in a few more days and some more miles and ill see what happens.
Also i am trying to burn off my tires and have a little fun so i can have a good reason to get some nicer tires
