Semi Slicks For Drags, To Much For Factory Driveline

[Jayden.K]

i want to get some semi slicks for the drags so i can hammer it off the line with bugger all wheel spin, but i have had a few people say that they have to much grip and either you will break you driveline or wreck you clutch (3000 rpm launch i do). anyone had experience??

hd clutch and currently have 210rwkw but soon will have around 250rwkw +

If you can't launch well with 250rwkw on street tyres, you are doing it wrong

Put it this way - I was doing 8200rpm launch limiter launches with 4x 275/17 Hossier Drag radials and 360rwkw in my GTR - I broke the front diff after about 30-40 of them in 2 days and put some wear wear on the clutch a $2000 Nismo Coppermix (which had already seen a good 200+ launches, and 3-4 years of work).

With 250rwkw and RWD you should be fine as long as the clutch is decent. If you have a cheap clutch and do some big RPM launches, then expect it to end badly.

Does your coppermix fade at all Ash? I got a single plate one, wondering how it'll like launching with drag radials and 330kw..

Im going to get a twin if I can sell my single one it time :-)

Nope... bog a launch and try again 5 seconds later and it still has no issues.

lol... Almost...

It did get a bit stinky if I did 2-3 runs back to back - and I'm talking full 8200rpm launches on radials. It was also near death so that wouldn't have been helping.

When doing normal launches on street tyres, it was a walk in the park - could do them back to back no drama.

There's more to preventing wheel spin than just tyres though, you can have 300 wide slicks it'll be useless if you have stock suspension and 5 degrees negative camber.

~180rwkw, Exedy HD clutch, stock NA box, tailshaft, diff etc. Wanted to run sub 9 seconds (1/8th) in a %100 street trim/street-to-track car. Had big traction issues first time out due to old cheap worn tyres. Changed to a pair of Goodyear Eagle F1's, done minimum of 30 3-4000rpm launches and using the clutch to prevent the car bogging down, had no driveline issues thus far, clutch and gearbox feel fine. If you have the stock GTT box I doubt you'll have problems unless you drive like an idiot.

tl;dr

-Slicks shouldn't be required

-Suspension and alignment are

-Driveline should be fine if maintained and clutch is up to it
