Who Has Notched Control Arms?

So much scattered info on this topic so I figured I would ask the question specifically to the people who have notched LCA's on their cars.

Next spring I plan on minitubing my car (myself) and am just trying to figure out what the widest wheel/tire combo I can have with just a notched control arm.

Not modified arms from gforce/Non-Sponsor but a notched arm. I'm well aware of these arms and they look fantastic but I only plan on running an 15x11 wheel with a 315 tire. I've been searching around and Ive seen a 70-80 offset mentioned with an 11" wide wheel wich equates to about a 8.75-9.15 backspacing.

Do you forsee any problems with this? Could I go 11.5" wide with a notched arm or would that be pushing the notch to an unsafe level? If I could get 11.5" and a 325 tire I would do it but its not a necessity.

Thanks for the help. Like I said I did a lot of searching on the subject but all the info on this is all so scattered that it was really hard to figure out.

Yeah Ive seen plenth of notches just cant figure out if i can fit an 11" wide wheel with just a notch or if I will need modified arms.

Also can someone move this to the suspension section? I feel like its a better topic over there.

Plenty of GTO's have been fitted with 11" wheels and 315s while only having notched LCAs. The full-on modified ones aren't really necessary unless you plan to go much larger.

11" wheel with a +86 offset and notched arms is no problem. I have MANY high HP Gtos on the road with them, no issues.

Damnit Josh, fly down here and do mine. I still have the notched arms ready to go on. Just have had no chance to bring the car to TN yet.

I'm in the market for stock replacements and trying a different route on notching them. Possibly modifying the arm completely and adding an eccentric heims for toe and camber.

I agree,give ours a look

That is what I'll probably do. I DD my car so cracking notched arms wouldnt be something I'm interested in. Besides with modified arms I can go bigger than a 315 if I wanted to. Plus they look so sexy. I still cant believe nobody makes an aftermarket tubular arm for our cars. Stupid GM only selling them over here for 3 years.

For those of you who have notched your arms, how did you go about reinforcing them? I'm doing mine soon and would like some peace of mind knowing their not going to break on me.

Anything past a 11.5" is going to be a struggle.

I was able to get a 12", after a lot of additional work.

Define...."a lot of additional work". Do you have any pictures? Just got my tubs in from gforce next up is a set of modified control arms from them. Anything else I'd have to do? If its too much of a pain then I'll just go with an 11" or 11.5" wide wheel.
