Need help with Carlyle racing 15" setup. Rubbing!!

[jasycz28]

With the Welds on from the floor to the bottom of the fender it was 28 1/2 inches drivers side and 28 3/4 inches passenger side.

That sounds lower than me.

My Welds and LCAs were rubbing last night. I have some custom spacers lying around, 5mm and I think 3mm.

[jasycz28]

I am going to swap in stock shocks and springs and see if that helps.

[Pro Stock John]

Mine didn't rub until I lowered my car 1.5.

[canecorso69]

Im lowered 1.25 and have no issues.

[jasycz28]

Swapped in the stock shocks and springs. Still rubbed on the drivers side. I am about to start a move to Oklahoma so I really don't have anymore time to mess with this right now. Once I get settled I will update.

We have not had any issues with cars at stock ride height and Weld wheels... if you lower your car (not recommended for drag racing) then you could have interference issues since the design was made for cars at or above stock ride height. With that being said I have seen many people run my kit on cars lowered but the amount you lower the car could create issues.

The recommended tire for this application is the Mickey Thompson 275 pro tire... anything wider than that could hit on the inner frame rail and/or on the lower control arm.

If you run a wheel with less than 7/8" of caliper clearance you will likely have to run a spacer.

Running a spacer will allow you to run a wider tire but we do have those sizes figured out as we designed the kit to be run without a spacer.

As for the Weld wheels, you will need to order the appropriate weld wheel with the correct amount of caliper clearance to clear everything... there are different pad heights from Weld and if you order your wheels with incorrect specifications you will likely run into issues. You can avoid this buy ordering your wheels from us at www.carlyleracing.com.

Also please note that we have seen up to +/- 1 inch of variance in tire sizes so just because they advertise a size of tire does not mean it will be exactly that... advertised tire sizes are done on a specific wheel size so if you are comparing two tire sizes make sure you are comparing them on the same size wheel.

I hope this information helps and if you have questions please call our shop at 888-307-9186 Monday through Friday 9a-6p EST.

Not trying to start an argument and at this moment I don't have the time to troubleshoot the issue properly. I have your 15" wheel kit and ordered my 15" Welds from you as well. When I bought your kit no where did it state that it may not work on lowered cars. I have a street car that I will occasionally take to the track and I love the look of my car lowered. Still I have gone as far as putting newer stock shocks with stock springs on in the rear and I still rub on the drivers side during soft launches. Maybe its because I am fat 230lbs. I have the ET street R bias ply 28X11.50-15LT which according to Mickey Thompson's website "should" be smaller section width and tread width than the rest of the 28" tires that fit a 15" wheel. I could be looking at the wrong tires maybe. I am at loss for the moment. I am about to start a move and will continue to troubleshoot the issue once I am settled.

I'll measure mine tomorrow.

Jasy,

I'm 28.7 from ground to fender lip, with 275-60-15 MT tires.

Double check to make sure your brake lines are not rubbering. The one at 3 oclock on the passenger side needs to be tied back big time, like real tight. PM me if you want to chat on fone.

Initially the brake lines were rubbing, I got those squared away after the first test ride. After putting the stock springs on it only rubs on launches even soft ones on the street. It could be the tires I am running as well.

Like I said I am moving next week and don't have the time to look at anything else. After I get to Oklahoma I will have another shop look at the alignment to make sure that is not the issue.

[Pro Stock John]

Have you pulled a wheel off to look?

I am going to pull off my RaceStar rims which fit okay, to make sure my other rims (Welds) fit. I'll text you my cell if you want to see pics or have any questions.

Damn.... I just ordered my kit and wheels from Carlyle as well. I asked alot of questions and they where very helpful but of all the research and calls this thread is the first mention of fitment issues with lowered cars.

I am probably too low on my coilovers to get a good launch anyway with the angle of the half axles but I didnt plan on returning to stock!

Im also doing a ZL1 diff conversion at the same time so ill report back and let you know how it went.

Any chance your wheels came with the wrong offset/backspace from weld? Maybe it was a clerical error on Welds part and not Carlyle as it seems they have done all the math and this is the first instance of a reported fitment issue.
