Trying to get the coupe set up to do some drag racing this summer and I think I am pretty well set on the Rancho RS99204 adjustable for the rear.

For the front I was thinking of a set of 6 cyl springs and I was wondering what the best shock choice would be, some sort of 90/10 I would assume.

Also for the front I was considering doing the air ride technologies shockwave v 3.0

I was consdiering this more from a ride standpoint but I'm not sure how well these would transfer weight at the track, they are double adjustable???? What do you guys think?

I went with some summit 90/10 drag shocks, and 6 cylinder springs.

Are the Rancho rears single or double adjustable? I don't know anything about them

I can ask my chassis guy what would be the best setup for your car, which is pretty similar to Kevin's '68. He'll be running a 347 this year as well. I'll ask him what he has in his car as it works pretty well.

You have Cal-Tracs now, don't you?

I don't have cal tracs. just 5 leaf reverse eye, rear sway bar and cheap shocks. up front I have 620's cut down, cheap shocks and sway bar removed.

It transfered weight pretty good before I cut down the 620's and put more stall in it.... I watched some video's of the only three passes I made this year on the new set up before I got my cage and the front didn't come up hardly at all. As compared to before in these pictures......

Anyone ever heard of a Monroe 58539 rear shock for Drag Racing? Supposedly it has a coil spring around the shock and a guy here in St. Louis uses them on his 66 with snubber traction bars and runs 10.70's with a nitrous 331 stroker. 1.5 short times with small slicks like mine...

The Ranchos are 9 way adjustable. Just crawl under the rear of the car and turn a little knob and you are done. This ease of tuning make them great for a dual purpose car.

Start with the knob around 1-2 for the street and around 5 for dragging--you will feel the difference.

Ordered the Ranchos, now I am going to order some 6 cyl springs and just keep my cheap front shocks for now. We'll see how well that works.

Thanks!!

Back in the day, guys used to take shocks, drill a hole in them, drain some oil out and put a sheet metal screw in for home made 90/10 shocks. These were not gas shocks of course.

I don't understand how you hook so well, ( lucky )but I wouldn't go to a looser front end unless you aren't hooking anymore. I would look at a slower shock, maybe even strapping the front down.

Is your part # right for your car? IIRC you have a 65' and that part # for the rear shocks is RS-99204.

I found a mention of these at Summit, but it also says they are not available.

http://store.summitracing.com/partdetail.asp?autofilter=1&part=RAN-RS99204&N=700+115&autoview=sku

Might want to call Summit to verify this.

HOLD THE PHONE! I think I just found them at Jegs (Jegs Part # 801-RS99204) The details are screwy though: http://www.jegs.com/webapp/wcs/stores/servlet/product_10001_10002_279520_-1

Otherwise, call Calvert Racing to see if they still have them in stock. They are great people to deal with. Contact info here: http://www.calvertracing.com/

yep. thats the same issue I was having. Summit doesnt have them "in stock" on the website it seems (it jus says N/A where it used to say instock/when in stock), and jegs looks screwy, just liky you said. I guess calvert is the next option.
