Mastering the art of the S197 3 link suspension (sixty foot)

[fin1]

Very impressive 60'! So you guys don't use an anti-roll bar? Makes me think ARBs are overrated. I'm using a TRZ unit now, and I've considered removing it. It's a great piece and very well made, but probably best for an all out race car--it's too damn noisy for me (makes the back-end really stiff and rattles on almost every bump).

No, neither Will (Redfire) or run an anti-roll bar.

[BMR Tech]

Very Interesting Chuck.

Seems to be working pretty decently huh?

I think that size tire, and the extra weight on your nose makes those settings react a little better then the '"average Joe" combination.

 

[router]

Kelly, Yea the 60" is not bad, I think I still maybe able to get a high 1.3 out of it. Just went to a WOT box also, so working out those issues now also. I highly recommend the Sub Frame Conn from you guys, Before, the torque boxes were making so much noise I thought I broke the seat on the first pass with the slicks. LOL

 

[BMR Tech]

Ha!

Yes, our subframes work exceptionally well for both drag and road racers.

Well good luck with the new parts, keep the site updated! I'll be sure to follow your results.

Will Do, I keep seeing info on Anti Squat brackets, do those help?

This looks very similar.

Yea, very close, you had any luck with the anti roll bar? I keep hearing people saying they are making a lot of noise if you are driving on the street.

It depends.

Some combos act differently.

A light, high rpm n/a combo might not see as much benefit as a 700+ RWHP lower launched, heavier poweradder combo.

Your combo, I believe they would work well.
