I think the springs were eibach. It was lowered 1.7" in the rear and 1.1"in the front. I couldn't tell you what brand the aluminum shaft was. I just know it was a 3" shaft and it was a one piece not 2. He also installed lower control arms and adjusted the angle of the axle. I'll see if I can get him to chime in.

I think the issue has more to do with lowering that changes the pinion angle vs changing the gears.

Yeah that's what I told him so he changed the angle. I sent him the link to the thread so he may say something.

Well if he can prove the 4 inch driveshaft is holding then AM might have a winner with the shafts they are selling.

Yeah I think hes scared to dyno it again lol. Each time it snapped it ruined the exhaust pipes so he just runs it on the track

thanks John for puttin me out here like that j/k... the DS was a 3.5" shaftmasters but we had only done the pinion angle at -1* (because the instructions said -1* to -2*) and it still snapped so now with the 4" i have it set at -2*... yeah i refuse to do any more dyno runs until i add more performance parts (LT's and o/r x-pipe) and have a couple backup DS's made just in case since i feel my cars cursed.

my time was fat-fingered earlier, i ran a 13.9 when i ran it in the quarter (horrible track prep was to blame) on 3.55's...a couple weeks later at a different track i ran an 8.706 in the 8th (should be around 13.5 in the 1/4 IIRC).

to the OP your next mods should DEFINITELY be gears and a tune at the same time preferably, really wakes the engine up.

Isn't the track just as hard on the DS as a dyno?

johngt10

That depends on how hard you launch and your launch depends on what tires and what rpm you leave at. Sorry ant lol. That's why I let kayla remember all the important things cause I can't remember details lol

ant speed

yeah John hit it on the head. the launch can be but running it you're not in one gear anywhere near as long as on a dyno plus there's much more air moving under the car to keep everything cool
