LCA Rubs Inner Wheel
I have a 2010 SS with quite a bit of BMR rear suspension products. The issue I’m having is my lower control arms (TCA028) rub the inner wheel of my 17” Weld’s both on the dyno and on hard launches. This has happened on three separate occasions that I can recall, despite the clearanced section that is designed into the LCA. The car also has trailing arms, toe rods, subframe connectors, rear cradle bushings and rear DA coilovers. I’ll add some pictures as well but I’m curious if anyone else has ran into this and what might resolve the issue.

It's tough to see in those pics. All but the last one looks fine. Have you replaced the bushing in the knuckle too? What offset wheels?

I’ll try attaching the pictures on this post reply and see if that works. Looking really close, the LCA is rubbing right on the lip of the inner wheel and taking a little bit of material off. The wheels are 17x10 Weld S71’s and while my receipt doesn’t list a backspacing, looking at their website it looks like 7.8 is the likely number.

I thought of a few things I thought I’d get some opinions on.
1) Would it make any difference if I swapped the LCA’s to each other side? 2) Would it be advisable to grind down the area of the LCA that is making contact for clearance? (Really don’t want to sacrifice any integrity) 3) Should I go with a different LCA and if so, what would be the suggestible options?

Can you get a pic of the mark on the LCA? I'm only seeing a scrape on the rim

It’s a little difficult to get a good view from the angle it’s at but I tried to clean up the area a bit and get as good as I can with my phone. Hopefully this helps some. I’ve got a few of the LCA and a few of where it chewed on the wheel lip.

SO, how WIDE are the 17" rims?
These arms are also shorter than the OE arms. The toe angle is being changed under acceleration. If the whole arm moved back with the wheel, it would not hit. You may have a bad bushing somewhere, and the knuckle spherical bushings are the weak spot. The spherical bushings are Upper and Lower control arm @ the knuckle, and inner UCA bushing @ the cradle. I recently replaced my knuckles because they were bad, and I have UCAs to go on because those sphericals are bad. Last edited by AlanRubin; 07-21-2021 at 05:59 PM. |

well, the back spacing is crucial in this situation. If you have a 7.8 back space 17x10 thats a fitment for 4th gen Fbody camaro's and C5 corvettes, i own both of them.
7.2" back spacing is the correct sizing for a gen 5 camaro. Weld Rts series has a fitment catalog you just have to match part numbers to what you actually have. |
