What Rim and Tire for Drag use only on '18 ZL1?

Jimabe · 07-25-2018, 04:33 PM

Guys

Had this under the ZL1 section, but suggested to move here...

Have done look-ups for drag wheel/tire here.
See the Weld 17X10, 7.2 Back Space is a recommendation for drag wheel. Is offset 44mm? This is for Drag racing only. I have an '18 ZL1. Again, looking for rear only rim/tire combo for the occasional drag event. I have a 1/4 mile track not far so would do a few times a year. Also, just got back from 1/2 mile drag so maybe use for this as well. Only issue i was reading is that some of you guys say a drag tire gets squirrely at triple digit speed. Since I get 160 in 1/2 maybe not for this application?...stay with my stock wheel/tires for that?

So, I'm trying to decide get another set of 20" rims for the back and put on a drag radial, or get 17's and drag radial on that. Guessing i'll have more options going the 17" route. Just want to make sure it clears everything...

Thanks

I'm going to go with a 17" wheel and tire for the strip. I haven't found the setup I want yet, so I can't really help ya. A few that had the squirrelly feeling reported that lowering air pressure helped. I don't remember what they started with, but apparently it was too high.

I am interested in this as well, I have a 2018 ZL1 also. I just bought drag only rims, I am cheap so I went with the race star 17x9.5 inch ones with the M/T ET street R radial, 305/45-17 I have read from a couple folks that this will fit! This tire has close to 3 inches more sidewall than the stock good years. My issue is finding a front runner... I am looking at an 18x5 with a M/T 28 inch radial. I read from a couple folks that said to try and keep the height of the rear and front as close as possible, that would be a 28 inch on the front. I dont think these skinny front runners have been put on the front of the Gen6 ZL1's or the folks are keeping it a secret as to what they are doing! I cant seem to get any decent answers...

Okay so with DRs/drag pack are you able to get below 1.7 all the time, or do the DRs just make 1.7s more consistent?

I am hoping for a little bit of both! My best 60 foot on the stock GY's was 1.739. I will have the DR's on it when I go to super chevy in a couple of weeks, we shall see what happens! now this is a different track and the DA could be better could be worse... who knows!

I havent been able to figure out the front runners yet so I will be running the stock GY's up front for this race.

I will go with Toyo R888Rs on 19" wheels and run therm all the time. Even with DRs ZL1s do not 60' very well, even the A10. GM bog for sure. A 1.7 like that is my best too but mostly 1.8s on the GYs.

Went to the drag strip over the weekend and really didnt get any better on the 60 foot with the drag radials...

the only thing that it did do was consistently stay in the 1.70's so I guess thats a bonus. The DA was 2800 there so my times were right around what they were with the stock GY's! I need to get some good air to really test these tires. I did end up putting some M/T skinny's on the front and I was quite impressed as to how they handled! drove 2 hours to the track around DC and was happy with it!

Fraxum, I am willing to bet if you borrow my 275/45r17s you’ll cut a sub 1.7 on your first pass

Currently waiting on doing our 15" conversion

GPI is working with aerospace currently on a rear solution should be ready in a month or two. The Carlyle kit is great but I haven’t seen any options that offer the weight loss benefits I’m looking for. Running a 15 is great but I’d like to get some weight loss as well aside from the smaller rim. Last I read the Carlyle kit was only worth like 7 lbs. the front kit I just did was worth 47. I woukd think a proper rear kit be worth about 30-35

how well does it stop?

My front kit seems to be doing very well so far. And stock brakes are easily swapped back.

It’s not for everyone but I like having the ability to run 15s and the weight loss incurred. Doing both front and rear brakes is nearly 100 lbs a lot of it rotating and over that with lighter 15 wheels. For me it’s an appealing mod

What front brake kit dropped 47 pounds from your car?

Aerospace kit from GPI. Rear kit is coming soon

12 inch (11.75 iirc) 2 piece front rotors and dual piston billet calipers. With the billet 15s I’ll be running over my race stars I’ll be saving about 60 lbs off the front with a lot of it rotating mass. With a rear kit and light 15s will be over 100 lbs.

https://gwatneyperformance.com/produ...ont-brake-kit/

They advertise about 40 lb drop. Snowblind weighed the components personally and found it was 47 lbs lighter
