As my signature line says I have an 08 Vert (stock), a 14 GTS (stock), and a 15 TA 2.0 with Arrow PCM, MCS shocks, headers and catback, under-drive pulley, Racing Brakes rear brake bias calipers (single best mod ever), 18 speaker stereo, K-40 Laser diffusers, Raptor shift light, white vinyl fang stripes, and TeamTech 6 points.
I use the 15 TA for the One Lap of America and track days. I traded my 09 ACR with similar mods for the TA right before the ACRs came out. I knew the ACRs were coming but that $15K certificate was burning a big hole in my pocket. Now I've been looking at a couple of ACRs that have caught my fancy.
My TA is faster down the back straight at High Plains Raceway here in Colorado than my old 09 ACR (146mph vs. 144mph) but they both turned about the same lap times. I suspect the TA with its lower downforce has less drag and hence is faster down the straight where the 09 ACR made it up in the corners. The 09 ACR also had ported intake and heads so I assume both cars are similar in terms of horsepower. My TA has been rock solid and burns virtually no oil even on track.
So the question is should I trade the TA on an ACR? I like the more aggressive looks of the ACR vs. the TA 2.0 and I do like the idea of having the king of the hill Viper. I would not mod the ACR given warranty issues that have been discussed here at length. That would mean it would have less horsepower than my TA (640 vs. maybe 700 in the TA). On the other hand it would have more downforce. I would probably look to buy an ACR with the TA's steel brakes or convert the CCBs to steel with a smaller rotor so that I would have many more wheel and tire choices. In any case, would the downforce be more important than 60 more horsepower at most tracks?
I cannot use the Kuhmos on the One Lap of America as they are not considered legal for the event. They would scare me in the pouring rain on an interstate anyway (even the PZeros were touchy in the 2015 One Lap when it poured in Colorado, Texas, and Oklahoma). Given this I must have more tire options and the tires must be street legal, no R compound or race tires allowed. i should also note that the PZeros seem to understeer worse than the Michelin PSSs I used on the 09 ACR. This is important as the One Lap includes two 200 foot skid pad events and they can and have influenced the outcome of more than one One Lap. On my old ACR I was in the top 10 on the skid pad but was mid-pack in my TA with the PZeros. It would not hold the radius with any throttle (maybe its the car and not the tire?). This is why I want 18" front wheels so that I can run Michelins all around.
Thanks for the input.
