I’m not building a track car or a drag car. My car will be full bolt ons E85 by the end of the month. Eventually I’d like to go cam and heads as well.

I’m looking to stiffen the chassis a little bit and upgrade the suspension just a bit to help plant more of the power. I’ve been looking at the single adjustable or the nonadjustable upper and lower trailing arms as well as the upper control arms. From my understanding the single adjustable can’t actually be adjusted while on the car. My question would be, is it really worth it to nearly double the price for the single adjustable arms, or will the nonadjustable get the job done?

I also plan on getting the front chassis brace and the rear cradle brace.

The single adjustable gives you a heim joint vs the poly. In theory the heim joint should keep things located better when under a load. I went with the single adjustable. I don’t know if it was worth the cost or not. I see some crazy fast cars with none of the bmr stuff.

Heim joint tend to be a little noiser than their poly counterparts.

With previous cars, my general rule of thumb was if you had to ask, then you probably want the poly. Even though those were on different vehicles, the concepts still apply for the most part. So take what I say with a grain of salt.

Thank you guys. I ended up calling BMR. Based on what’s being done to my car as well as it being predominantly a street car, they advised the nonadjustable. They also strongly recommended the cradle lock out kit. According to them, the two biggest bangs for your buck are the lock out kit and the lower trailing arm. I was able to order them through RDP for a great price.
