First, you'll need to get a feel. I'm not the best to respond, but I'm going to do my best and tell you what I think with mine. As I said, get a feel for each gear, slowly, at first before just ripping on it. I actually took 1,2, and 3 to the top speed they could do at red line, so i have an idea of what a good run might look like without having to think to much. I know I'm doing well when I hit ~62 in second gear, that lets me know I'm getting on it well. I drive to 5800 each time. 1st gear, launches... depends on tires, gears, and clutch even i would say. I have a Spec 2 on a TKO500
trans,aluminum driveshaft, and 3:73 with a limited slip in the rear as well, so I don't have to worry about hurting any of that. But with my T5 i had, launch about 1500-2000 on street tires, from 2000 it'll still drop to about 1500 and traction should be alright, 1500 launch will just be on the safe side. Shift dilgently but, don't "throw" it around, mean it! Watch wear you're putting it in... Third (for me) is the one I think about the most if any. But after a while, as I do now, I just watch my tach. I don't want to ramble to much, as i said earlier, I'm not the best driver in my opinion, but wanted to give you some heads up. Best of luck, and test when you can and let your conscience be your guide, hahah safe driving!
