Drag Racing Launch set up and times for Manual Transmissions

phunk

I was about to say that the ET Street R is a radial rather than a bias ply, but I just went to their website and see that the ET Street R is offered in both now, and both DOT... interesting.

I went through a set of 17" ET Street R (radial) on my SC'd Mustang. When they were NEW, they gripped like crazy. It would dead hook second gear at 815whp when they were fresh on nice concrete. Never tried them at low pressure with a burnout to see if first could hook. I'd imagine the Bias version will probably do a little better.

If I had to guess, that tire might be able to hold anything a FBO Z throws at it. So long as your suspension is setup decent enough, your tire pressure is dialed in, and your burnouts are good... Its probably plenty.

I wouldn't call my drag racing serious! I merely showed up with a twin turbo Z to a drag strip 2-3 times, and its been 5 years since I last did that. A lot of people tried taking a Z like mine to the strip over the years, and the crappy results seems to keep most from trying it again. The only extra step I took was to try the small brakes and big tires thing, and I had a little extra success with that (got the 1/4 record at the time, 5 years ago). I started to wake up about what had to change after that, but never tried it again. A couple years later when we were experimenting with Justins car was when we realized that the 370z really can hook decent if we stopped ignoring what the rest of the world always knew about slamming cars and trying to drag race them.

Well I did figure out that my camber is -4% in the rear after putting my coilovers on. So, I'm sure that was a huge part of my 6 second 0-60 runs.

I have been planning to bring it to the race shop so he can corner balance and we can talk over my set up for drag racing and normal driving. But, I am finishing up my build first! The intercooler and turbo set up add a lot of weight to the front. So, I need that done before we corner balance.

My R888r's come in tomorrow for my stock Nismo Rims (putting 305s in the back)(hope they fit). I will be ordering some rims and tires for a drag set up after I talk to the race shop.

The tires will fit fine. I have RE11's: 325/30/19 on my stock wheels for the rear.

I forgot I said I would update this.



1.68 60ft
28x10r17 M&H bias ply slicks @ 13psi
1" lower than stock on Fortunauto 500 coilovers set to full soft
Launching at 5krpm with 4psi off the line, I had the rear suspension preloaded with the hand brake. I also have a line lock for the burn outs

The next race is on the 23rd. I have resigned myself to 4x4 status and will be raising the car up to stock height, taking it to the alignment shop and have them ratchet strap down the rear of the car to simulate the launch and go of as little negative camber as I can get away with while trying to keep the ride height camber below 0. I am hoping this, more boost and a psi or so less in the slicks can get me consistently in the 1.5's

Do you have sport brakes and if so what 17 inch rim worked for you?

sirnixalot

Yep, sport brakes all around. I am using some Forgestars meant for the newer mustangs. 17x9.5 I think and 44mm offset. They clear everything just fine.
