I see alot of the USMTS guys running there lr clamped. Which is better? Whats the pro's and con's of each?
In the bob harris tech video kelly said you can get more bite with it on the birdcage, but on his cars they are clamped, am i missing something?

with the left rear spring clamped infront of the rear end ittries to compress the spring and adds bite to the left rear under power.

Also with it clamped it's alot easier to change bar angles with out effecting birdcage indexing as indexing is not a factor. I'm pretty sure that's why Kelly's cars are like that, they are alittle easier to adjust to most track conditions.

Ill second that!! also on corner entry the chassis drops and so does your spring mount which will tighten the car up on entry..
And the reason Kellys car is like that is because the Pierce cars are like that and that is what he copied the rear of his car off!!

I know a guy who just went back to the clamp bracket on his late model. He said the car is much more driveable and easier to adjust. The car only wants to get up on the bars when you are on the throttle. The guy that convinced him to do it said with the spring on the bird cage the car can be really fast but is harder to get the set up right every time. It seems to work good for the pros that race a ton and have full time crew cheifs helping.

It is all what the driver likes, With our lr clamped we run less bite.

My new car is clamped so it's new to me, I have always ran it "ON THE HOOK" and loved it.
