You know...when I decided to try some different stuff with the Vette...not sure I thought it out real well. I've always run around on the street with some basic BFG street radials and some tire store specials on the front. I've blasted past 150 MPH quite a few times on that stuff.

For the dragstrip...I've got a set of M/T wheels with some 10.5x28" slicks and some M/T front runners on some Bogarts for the front.

Then I got the wild idea to run that half mile runway deal. So I got some M/T drag radials and scrounged up some V-rated front tires. All was good....managed 177 MPH.

Then I got the idea that if a little is good...more is better right? What could I do in the TX Mile? Well...that brings another issue. They don't allow drag radials and to sneak up on 200 MPH you need "Y" rated (186 MPH+ tires). Finding stuff in 15" diameters for those speeds isn't too easy...but I finally found some roundy-rounder tires approved for those speeds. When they arrived...I found the fronts were a little too wide and weren't going to clear suspension and fender properly. Bummer.


So then I finally located some Pirelli Y rated tires for the front. Short little devils but they should help keep the nose out of the air.

This weekend is preparing it for the drag strip next weekend.....then if all goes well I'll switch everything around for top end playing.


Probably should have planned this a little better!

Perhaps you would be better served to do away with 15" wheels for specialty situations. Just keep them for shows, normal driving, and stock stuff.

Probably so. For drag racing and street cruising...nothing works or looks better to me.

For the high speed stuff it would be easier...but not enough tire height to hit the big speeds without O/D. Still trying to decide if I'm going to swap some gears in my trans to make it O/D for the TX Mile.

OD isn't the safest way to get speed I was always kind of worried when drive line rpm was aproaching 10,000 rpm

Bonneville uses rears like 2.73 or less to exceed 200 mph with 1:1 final tranny ratio

How tall of gears are available for the Dana 60 Jim?

I have almost the same "tire store" for my sand car. Street, dunes, and desert, and a specialty tire or two....

Technically 3.54's. We modified a set of 3.07's from a Dana 61 to fit into the Dana 60...so I've already been pretty creative!

A growing tire/wheel stockpile is yet another symptom of the sickness we share.

So what do you have to keep the nose from lifting on a C2 lol

I'm going to drop it a little lower. Keep the front spoiler in place. Crack rear of hood open. Maybe block the grille. I'll dial shock rebound up high and compression low.

It it really didn't seem so bad at 177 mph.
