Hey guys,
I just got new wheels/tires for my TA. I got BF Goodrich G-Force in the front and KDW-2's in the rear.
When I take my TCS off and smash the gas pedal nothing happens anymore, tires wont even spin..........is this just due to new tires/wheels???
I got a 17/18 combo, Centerline wheels.......maybe the weight is makin me slower???
I dont know what it is, but its pissing me off.........my car used to seem fast as hell when it had the piece of **** stock tires/wheels it came with! haha

more rotating mass plus the new rubber has more grip. i wish i had that problem

Looks like I need to start modding up under the hood and exhaust next!

yep....always a good idea

the big wheels definitely slow you down for sure. going from stock 16's to 18's will probably net you a loss of ~0.5 in the quarter mile, not to mention a drop in fuel economy. of course, this is assuming an equal launch. since you'll get better traction with the 17/18 combo, maybe you can even the score? either way, you'll probably go a little slower and definitely lose some mpg's. but hey, you look a lot better now i'm sure

No...I dont buy that, otherwise SS's and WS6 cars would be turds. If 2" is = to .5 then 1" (16 to 17's) is worth .25 and we all know that SS/WS6's run THE SAME TIMES as their other siblings. He is just getting more grip, tire weight wont matter a hill of beans at 0 RPM (which is what they would be turning when he first punches it ) IF they wont break loose, I doubt it is teh extra 20# he added to the rear of the car with rubber/rim. Its just the grip. I do find it odd that you cant burn out though, my 95 LT1 A4 2.73 on clean asphault would LIGHT! them up with new Cooper Zeons (not as good a tire as yours, nor as wide im sure (245/55/16), but I still hot a TON! 43.5' * of wheelspin, all with the 3200limiter lol).

Let me guess its an A4 with a 2.73 gear?

My car (A4 with 2.73's) I found that the stock converter and good tires would not spin them at all because the car starts out well below the LS1's powerband.

LT1's make power a lower RPM plus (at least comparing my LT1 I used to have vs the LS1 I have now) the LT1 would come on the power like a switch while the LS1 feels smoother.

If you want to light them up get a good stall... my car 2.73's, 3600 stall, street tires + full throttle = insta-burnout.

98Trans

Yes, I should have thought about that. I have an A4 with the 2.73's.........I want to run a 3200 stall with 3.73's eventually. Looks like I might be doing that sooner than I planned!
Thanks for the comments guys!

BLKWS.6

Wow...so launching an LS1 car is a lot easier b/c of the lack of power down low compared to my old LT1/mustang GT (and WAY better tires than the GT)?

98Trans

Man, you can literally pin my gas pedal to the floor and theres no way you could lose control with these 18's in the rear. It kind of sucks, I want new gears and a stall, now!

I could roast my tires all day long with even moderate acceleration off the line when I had Kuhmo Ecsta's but now that I have BFG KDW2's they just hook. I'm sure I could spin them if I wanted to as I have a stick but I just see $$$$ when I see people doing burnouts. The whole idea is to get the power to the ground not to fry your tires anyway right?

Get it on the Dyno and see if anything is wrong. If the HP is low you know something is up.

I have KDW's. My manual can make them spin all too easy. I am not talking about a massive clutch drop. As low as 1800 I have seen them break loose. It is really annoying in fact since I am not really a burn-out fan. I prefer to have control and leave competition in the dust then do a massive burn out (standing still forever) and looking cool to teenies.

Going back down to stock sized tires makes me seem faster from a roll but I can't launch with a $^#@$%^@ as compared to those G forces on the Corvette wheels!

This is a big misconception, and has been beaten to death many times. LS1s have a very linear torque curve (most of the torque is made off idle), so they don't "feel" as fast down low. Hence, people thinking an LS1 doesn't have much low-end. Someone posted a graph of a stock LS1 and stock LT1, and it showed the LS1 actually made a bit more low-end horsepower. The search is working now, so you should be able to dig up all those LS1 vs. LT1 threads.

How is your launching/burnout experience going with your Red Z28, Iron Sights?

Iron Sights

Great! A quick slip from ~1900RPM gave me a 4 car lead by the top of first on a twin-turbo Audi S4. I expected him to put up more of a fight (AWD) even with the automatic. My tires will break lose depending on the road I'm on. They usually light up at about 4000RPM in 1st, but sometimes sooner if the road has less traction. That's going to change this winter (cam and longtubes).
