I'd mostly go to CAM because if I'm going to invest in new wheels and tires I'd have to stick with 19x10 wheels up front to stay in street class. Also, if I want to use the GM rear diff autox tune that makes the car ineligible for street. I'm not that worried about being competitive in my class and I don't care about PAX at all. But after driving the car for a while I think the larger wheels/tires and rear diff tune would make the car more fun to drive and it would certainly be much faster. It also wouldn't take away anything from it's use as a street car. With this setup in CAM I'm pretty sure I can beat a vast majority of the Mustangs anyways, I think I could be pretty close to the top of CAM-C in my region without any other mods. The car does really well in BS bone stock, even with my questionable driving skills... and as long as you can get some heat in those GY SC3s! Last event was a BMW autox, there were about 20 cars in BS, I would have come in 3rd, missed 2nd by a few thousandths. I got 2nd in open (all non-BMWs, class had 17 cars), but that's based on PAX, there were some faster cars in raw time. 1st place was a GT4 on RE71s with a pro driver at the wheel.

Glad to find this thread. I'm new to the 1LE and this forum, and just ran my 1st event in a new (to me) 1LE this Sunday...on MPS4S...which has led me to immediately shop tires Our local alien driver runs on the OEM SC3 20" and suggested they are really not much slower than the 305/30/19 RE71R setup. What sort of time difference have others seen between OEM 20" SC3 and a 19" square RE71R setup? Last edited by CRBWS6; 09-25-2020 at 11:30 AM. |

IME it needs to be 80+ and sunny for the GYs to work, and then it'll take a couple runs. Mid 90's+ is what it seems to take for them to reach optimal, but when they are, they are really impressive, as is the car.

*When you move them in for max camber at the event, you'll also gain some toe out. If you set toe to zero for your street camber, then this could work in your favor because a little toe out seems to increase front grip (at least on my car), but increases inside edge wear in street driving. Quote:

Loving my new 1le! I knew I should have ditched the Stang a couple years ago. Here is a video from NWR SCCA event last weekend. Was ~60 degrees and overcast. SC3's took a run or two to warm up but then felt great!

I run CAM-C in my '18 with limited mods mostly because I don't want to spend the money. I do fairly well in class when I don't mess up. Driver definitely needs more work. when I'm on my game, I usually PAX in the top 30 of 130ish drivers. Not bad considering all the previous national champs in the Cal Club region. My mods are 19x11 apex wheels, BFG Rivals, Vorschlag Camber plates, GM eLSD tune, and a Mamo PTB. I've thought about going to 18" wheels but some of our courses currently take me to 6400rpm in 2nd gear. Not sure what that would do with 335/18s.

It can sometimes be 40-50 deg at 9am in the AZ winters! I am coming from an STU car on RE71R and would guess there was about 0.5sec penalty by running the A group vs. later groups. |

Oh, I agree completely. The extra power is for...other times than autocross runs.

I really have no desire to get more power other than what could be achieved thru e85 and it's tune. An intake and axle back would just be for my pleasure. I'm not sure if the PTB added any real power gains, I got it for the crisper throttle response on idle when on the street. It does pull a little better to redline but I didn't notice much at the autocross. Right now I'm just trying to work on my driving and tuning the suspension a bit. Gotta try to keep up with the Wongs, they are running CAM locally now instead of ESP.

Due to oil pump boom, I need to get alignment redone - what is consensus on toe in vs toe out at the front ?
GM track setup seems to indicate positive toe.
