2nd gen subframe

[81 trans-am]

I know its been talked about before but Is there really a benefit to the aftermarket subs when it comes to performance. I love the look but the price sucks. I want a capable car that has all around good performance but 5-7 grand seems a bit much. I plan on a 3-link out back and c6-zo6 brakes. But the front has me stumped on which way to go. The car had bmr stock geometry tubular upper and lower ca's with qa1 single adjustable coilovers. Iknow there are better setups and just would like some other educated pinions.

thanks
