im trying to get my 60ft down. on my best et ive gotten a low 2.1 60'. for suspension all i have is eibach prokit and tokico shocks/struts for now. the tires im running are eagle f1 GS-D3 17x315's. ive been putting the tires at 20-22psi(not sure really where to put these tires at) and doing a brakestand till the tires get smokey on the first pass then usualy just cleaning them before the next runs. i launch usually at around 3k. any advice would be welcome.

Don't burn out on street tires unless they're a near R compound tire, which GS-D3's are not(there's only a handful that will actually get sticky(er) if you do a little burnout). Just a quick scrub for 1-2 seconds tops to clean them, anything more and they get greasy.

Avoid a burnout like said. You can spin them once to get any dirt off. You can probably pull a 1.9 out of street tires but the lowering springs aren't working to your advantage. Practice is the biggest thing. I completely suck at launching but just practice a lot and slip the clutch.

If you're leaving at 3k you're gonna have to slip the hell out of the clutch on street tires. I'd either try to slip it more, which is killer on a stock clutch, or just launch a bit lower and slip it. Either way, you're gonna bog and then go, which is all you can expect on a street tire.

thanks guys. i guess the only thing i want to know is where to put my tire psi at. im going this friday. i think im going to set it closer to 25, usually i put it close to 20.

closer to 25 id say, lower will cup the tire, causing less contact area

When i was running street tires, i tried different tire psi, ranging from 20-33 psi. It really didn't make any difference!

On street tires, and stock suspension...no matter how you launch, you'll be extremely lucky to beat a 2.0 60ft. imo.

even though you have a wide contact patch those tires aren't the stickiest, 280 treadwear. a couple of good things have been mentioned already, lower rpm and slipping the clutch is probably what you need to do. if you're not getting wheel hop try just letting it spin enough to where when it catches it won't bog and see what that does.
