My car is a '11 Mustang primarily used on weekends from end of March until just after Thanksgiving. I have updated multiple suspension parts-
Lowering springs, struts and shocks, rear (adjustable) upper and lower control arms, adjustable front and rear sway bars, adjustable end links, adjustable panhard rod, GT500 bushings, ball joints.
My question is-Is it worth upgrading the factory front lower control arms to an aftermarket tubular/adjustable set up?
I'm putting together my list of off-season mods and this is one of the items I am considering.
It depends to be honest. The only real reason to do so is to lighten up the front of the car and depending on what kind of racing you do if any would necessitate the need for them.
If you plan on road racing a lot then the option there would to go ahead with the Boss 302S front control arms. While they a bit more expensive (and heavy) than the BMR A-arms, they are made of a heavy duty steel with ball joints that are something like 20mm taller than the factory ones.
While there are people that claim the BMR A-Arms will flex a lot while seriously tracking your car which will cause your suspension geometry to be off, I decided that for my needs the BMR A-Arms with the A-Arm support brace will help shed some weight and add a little bit more corner stability than the stock units. The adjustable setup is nice in dialing your geometry of the front suspension but unless you are REALLY going to need it than I wouldn't worry about it too much.
