Looking to buy LCA's for the rear. There's so many different brands and theres adjustable, tube, boxed, sperical end etc. I'm looking for drag racing application as I'm trying to get to the 12's. Car is driven about 3K a year with a couple of trips to the track. Also I've heard you can get really good rear shocks for cheap from Summit. Any idea on the part number so I can order them

 

Dont know the part numbers but i know the drag shocks are 28.00 each. If you search you will find them.

As for the LCA's, the basic bmr's should do fine for 12's. Now if you wana run 10's and plan to stuff some 28 inch slicks in there the adj. boxed ones may be a better fit.

If your handy and have a welder you could box your stock ones.

In my opinion, there's not a whole lot of differences in the brands of well made tubular LCA's. I would recommend the tubulars for their light weight, and for the added clearance for really wide tires. Adjustable is generally only needed if you need to move the rear axle front-to-back for tire clearance. Make sure you pick the correct "ends". Poly for low price, and moderate street driving. One poly end and one rod end for a bit more control at the strip, and to avoid bind when cornering. Rod ends on both ends for maximum control, but also the harshest, nosiest ride. Rod ends also wear over time. There is one vendor with a spherical poly end that seems to work well. Chrome moly is generally only necessary for the absolute last ounce of weight reduction.

A qualtity LCA will use top end components - particularly the rod ends - and will be welded by a pro. You will find that the Spohn and BMR components meet these requirements. I've seen the Spohn tubulars, with his (standard) high quality rod ends, push a 3,500# F-Body into the low 8's.

 

Thanks for the input, last time at the track I would hear a bang when the car hooked so I think the LCA's will cure that. I was all set to get some boxed but will now go with the tubelars for weight.

 

I got all my stuff off Ebay and has really helped. I get perfect launches everytime and the Slicks cut 1/2 second off the 1/4 mile. All the parts are SLP except for the BLM relocation brackets. Paid $350 for them all including the sfc.

 

Brent Darroch, Joe Russell or PeteZ for lower control arms.

Summit sells a 3rd gen shock that works awesome in a 4th gen.
