QA1 or PST for upper control arms?

[grjammer]

Trying to decide which is better. Leaning towards QA1, but would like to hear any experiences with these arms. Running bbp single caliper disc brakes on 25/26 inch tall tire combo. Switching to 1.03 bars since I am installing a 440.
Any success or horror stories out there?

Get the ones Peter Bergman sells (Home - Bergman Auto Craft - Home of Quality Muscle Car Parts). You'll be glad you did.

thanks for the tip, those look very versatile and should be at that price!

Yep, you can dial in just about as much caster as you want.

I've used both QA1 and PST arms, and I had no problem with either of them. The only problem I see with the new equipment, not necessarily QA1 is that some of it "might" be made in China.

Assume you mean the double-adjustable SPC's from Bergman's. I got those from him for the avatar and 2nd the recommendation wholeheartedly! Been on the car over a year. They do not require retightening - just dial in the alignment numbers you want and go. Love'm!

I have QA1 uppers on several cars and have been happy with them.

Thanks for offer, still researching options.

Our arms are simply the best available. We offer 3 levels. All of these offer delrin bushings and the widest adjustment range possible. None of these require contorting yourself to reach eccentrics that have very little range. Our mid range and upper range arms also feature taller ball joints. This improves the camber curve. This means when you go into a turn, it allows the outer tire to mountain its contact patch. Our top level arm is the only forged arm on the market.
