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 :P

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..

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

      spot the stagea

      It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack.

      Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.

      In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).

      ECUtalk pages don't mention they support the ABS computer (consult port has more than one CAN), so you might just need a different scan tool. But, I would expect ABS is a different light to the brake warning/handbrake light, do you see an ABS light come on for a few seconds when you turn the key from ACC to IGN? But since you said: I'd have a look at the ABS sensors in the rear hubs to make sure they are not damaged, disconnected etc.

      OK, if it idles at 1000+ with the AAC, its not an idle airflow problem. The cold start valve just gives extra air when the engine is cold, but you have enough air without it to idle at 1000. I think you are back to a fuel problem, sorry. Can you see the fuel pressure staying constant or does it drop as the revs drop to a stall?
