I had a 3 second per lap difference at COTA between SC3 tires vs. SC3R on ZLE wheels on my SS 1LE on the same day with conditions being very similar and the car setup at the time was more optimal for SC3s. I imagine a ZL1 would definitely be noticeably faster with the long straights at COTA.

Warranty is very valuable when you track the car a lot and the 3R tires wear out around twice as fast as the SC3s on my SS 1LE and MPGs should be 5.x instead of 3.x on track so you should be saving significantly on consumables. Enjoy!

Keep an eye on the front bushings. When they leak, the ZL1 1LE FEA control arms are a popular replacement since they have solid bushings.

Thanks for the tip! I will probably just go ahead and order a set now. EDIT: How about the SPL lower control arms vs the FEA ones? Is it worth the $500 more?

I didn't mention, the car is still on stock alignment too. I plan to do the camber strut mod soon too. What is a good amount of camber for SC3's and SC3R's? I was thinking around -2.5.

Nice! I considered a ZLE upgrade but it's not worth the cash for me. The ZLE costs A LOT more to run, to insure and to buy upfront. It makes more sense to just buy a real race car at some point. Camaro GT4Rs might come down in price eventually...

-3.5 front/-2.5 rear with zero toe front and .05" toe-in rear would be a reasonable place to start. I'd get SPL rear toe arms and Vorshlag camber plates to facilitate alignment. Also, the ZLE rear cradle bushings are a nice upgrade, as is a stiffer front roll bar.

After going to the track today, I wouldn't go back to a ZL1/ZL1 1LE over an SS 1LE unless you frequent a much higher speed track. Even then, the SS 1LE is still a way better "bang for buck" car. Consumable costs alone will be worth it to me.

I already have the SPL full rear arms and Vorshlag camber plates from my ZL1, I just haven't installed them yet. I put my DSC sport suspension controller in on my 3rd session and it made the car feel like shit. It felt floaty and unstable. I pulled it back off and was back to normal.

Well fellas, It looks like I made the right decision (for me and my local track at least). I did my first track day today, and wow! With no aero, smaller 285/305 tires, SC3's vs SC3R's, 300 less WHP, and no suspension mods, I am 1.16 seconds slower than my ZL1 (On my very first track day)



First impressions: You can really feel the weight difference, Corner entry speed/exit speed is higher, I can get back on throttle way sooner, and braking feels about the same even with the smaller calipers/rotors.



I think with the 305/325 SC3R's, the car will be just as fast if not faster than the ZL1. My local track is pretty tight overall (has 2 decently log straights) and I believe the difference between both cars would be much greater on a higher speed track like COTA.

Congrats! As an SS 1LE owner this makes me happy to hear. I’m glad you are enjoying your new car. As you stated earlier when it gets hot outside you’ll love the SS even more. I bet you are enjoying that big fat check you got on your trade in as well

IMHO, no, the SPL radius rods are nice but not worth/needed for a street/track car. The ZLE radius rod is going to be a durability step up from the SS 1LE. And the lower control arms are the same between the ZL1/ZLE and SS 1LE.

I thought the SLE had the fluid-filled LCA bushings and the ZLE ones were solid?

I was considering the SPL LCAs, but they are expensive and I don't trust the overall design, a bolt instead of the ball joint on the knuckle end is not ideal, especially if spaced out to change roll center. A few people have managed to break the bolts, and some of their other products have had durability issues. I'll keep my rear toe arms and roll bar links, but I think those are the only SPL parts I'll be using.

i have the full spl parts kit and had it on about 4 years now doing about 5-6 track days a year and never had any issues with any of my parts

Yep, the SS 1LE radius rod bushings are fluid filled. Radius rod being the diagonal front lower control arm. The ZLE's bushings are solid and more durable with super grippy tire use. The other front lower control arms are spherical bearings, on the SS 1LE, ZL1 and ZL1. Same part #.

Yes sir! The ZL1 was paid off, so it was all just straight to the bank account.

The SS did amazing and didn't feel it pulling power at all.

Is anyone running YYZ springs on track? I am curious if there is anything negative to installing them. Ride height is a bit high for my taste, and I want to install my Vorshlag camber plates anyway. I probably won't do anything till March/April though. I'm about to be working a lot for the next 2 months.

I have a set of BMR springs I'd almost give away. I went BMR because there's more rear drop than front, after you do camber plates and adjust camber I think you'll find the front end will be lower and there's more rake. I ended up buying coilovers and never used the BMR springs.

Ok, thanks. Radius rods are the arms the brake cooling deflectors mount to are and the ones that leak? The "real" LCAs are spherical on the inside and ball joints on the outside?

I've been thinking I should just get the ZLE FEA arms and do it preemptively...
