Hey all, looking to get some help with what I should do about my new build. I'm about to get the car back from the tuner and it is gonna be around 550rwhp. Im worried about putting new control arms on the rear as well as not having any torque box upgrades as i dont want to cause any damage. The TQ boxes look fine now but the car only had 350rwhp before. The car is simply a weekend street car, no track time whatsoever and it might see a drag strip (with street tires) in the next year or so. should I not worry about it or spend the enormous money and upgrade? Shop said the torque boxes would be about $1000 to reinforce and i was thinking some sr performance control arms (mainly for the new bushings). Thanks for the heads up
