Should I ladder bar or 4 link

To the OP. How much front suspension travel do you have? Shocks? Mono leaf springs to go with the Cal Tracs? IMO you'll be wasting money and time installing ladder bars on that car. There is no reason that the Cal Tracs won't work.

I ran 6.50 with a 1.43 60' on radials on an un prepped track at grudge night with 9 way Rancho shocks. This car with less motor has been 1.38 on a good track and 1.40 in street trim. I'm hoping when I get my converter back to go some low 1.30's after tuning.

If I ever step up to big power I'm going to a four link and be done.

I am unsure on the front end travel. I did change to a magnum force suspension with coil overs and this limited my travel versus the stock suspension that came in the car. Thanks to everyones comments. I think it boils down to personal preference. I am leaning towards a 4 link mainly because of the adjustability that comes with it. So if I do upgrade over the upgrade I plan on doing this winter. This will be the best decision for me.
