ReevZL1 Build
 

It's been a long wait but here's pics of the Welds Racing S71s on my 2018 ZL1
Purchased from Carlyle Racing.

Front wheels and tires: 20x7”, 245/45R20 Mickey Thompson Street comps
The 245/45R20 tires do rub slightly on the inner fender well. It does not make noise while doing so, but Les Schwab Tire pointed it out to me.

Rear wheels and tires: 17x10" 305/45R17 Mickey Thompson ET Street Rs

Wow those are some sticky tires. Sticking to the ceiling with ease.

That drag setup is sweet, I have the dark star wheels with 17s in the rear and 18 in front, the 17s actually look really good, and yeah I can’t jelp with the pictures on why they are like that, I had to put my phone on the floor and walk over it to see these correctly lol

Thanks i dont know why they wont post correctly. I even flipped the pics upside down saved them and reposted with the same result, upside down. Very frustrating.

Reev, I'm half in the bag now, you're really makin' me dizzy.

I have the same problem. I have an iPad and take pics with the home button on the left. Try it with the home button on the right and see how that works or google it.

Factory lug nuts do not fit the Weld Drag wheels so I purchased the Billet Lug nuts also from Carlyle Racing. Cost was $239

TPMS sensors
 

I also installed GM TPMS sensors in the front wheels. However Les Schwab Tire could not get the TPMS air valve stem to seal on the Bead Lock rear wheels. They did say if the stem was rubber instead of metal it would work. Currently the car only reads the front wheel tire pressure. I do have the low tire pressure light on my dash lit up.

Weld Racing Wheel Weights
 

The 20x7.5" Weld's weigh 22.2lbs each and the 17x10" with the Beadlock weigh 24.2lbs each.

Exhaust
 

For exhaust I went with the ARH 2" headers Black Ceramic Coated no cats from Weapon X Motorsports cost: $2,138. I also went with the Borla Atak cat-back system which is on backorder. Borla pushed back my shipping date 3 times because they were using GM Valves and they didn't work. So Borla made their own valves and I'm currently still waiting for the shipment. Borla does not make an axle back exhaust for the ZL1 only cat-back because it's all one piece from the cats. Cost for Cat-Back was $2,150 from Jegs High performance.

5" CAI
 

For CAI I went with Weapon X Motorsports 5" CAI "Tune Required" version. Cost: $599
