I have a 1998 ws6 with 48K. In the near future I am going to have to break down and get a new clutch. Due to bad driving (not heating up the tires using brake and gas ) 5yrs ago I killed the life of my clutch. I have since changed my ways, but the best I can get at the track (havent gone in 2yrs due to slipping clutch) is a 12.2/60' 1.85 @ 118mph with 100shot of gas.
My question is what all parts will I have to up-grade by having a 1998? Also, what upgrades (such as light weight fly wheel) are a waste of time and money. I only plan on going to the track a few times a year and I only drive the car 5 to 10 miles a day. I am the only one driving it so if the clutch peddal is stiff it will not bother me. I am sure everybody is sick of people not doing there research and just putting there hands out for the golden egg set-up, but I have been trying to find and look up options. I would just like to hear what yall think. Thanks in advance
