Do not listen to Handz.
Handz has MM
suspension, I have UPR. Handz can't hook 400rwtq on street tires, I can hook 460rwtq on street tires.
MM stuff is good for autocross, not drag racing. Get on Yellow Bullet and talk to the big dogs of racing. You will notice a lot of cars that are running 4's in the 1/8th on drag radials are running either Team Z, Wolf Race craft, or UPR
suspension.
I have had my UPR
suspension for a while now and love it. 98Cobra281 has had his for awhile, and as far as I know, he loves it. I've drove my car from Russellville, Ar to Fishkill, NY and back to Russellville, Ar. Then drove from Russellville, Ar to Plymouth, MA and back to Russellville. Drove from Russellville, Ar to Myrtle Beach, SC and back to Russellville, Ar. Drove to Miami, FL and back to Russellville, Ar. That's just the long trips I've taken. Been to Texas, Tennessee, Missouri, and Kentucky in my car. While traveling to those places, I have had UPR's pro series rear
suspension on my car the entire time. I have yet to have an issue. Not to mention between those trips, being at the track cutting 1.5x 60ft times.
Like I said, I would go with UPR.
