I have had a LOT of cars over the years and drag raced most ALL of them. Many on drag radials.... BUT this car to me on 18" MT drag radials is VERY unsettling... feel like I am making corrections all the way down the track.

Anyone else notice this or am I nuts? Or maybe my particular set of Drag Radials are not the norm...

There was a guy in this thread who had similar sentiments. I still don't see the difference and as you, have street driven thousands of miles on 15-18" MT ET Streets with no issues

My car goes straight as it did with the stock setup...What is your setup? I'm running 345/35/18 M/T's on rear and M/T's sportmans 26X6.00R18 on fronts. I know if your running a drag radial in rear with stock fronts that could deff be doing it!

Stock front wheels/tires and rear 18x12 wheels with I think 345 rear MT's not sure have to look.

I'm wondering if wide stock fronts is the prob. I know in the old days with ET Streets bias tires you would need to run bias up front but didn't think would have issue with radials in back.

Nothing out of the ordinary to me...

I'm running MT 20" DRs and noticed on the highway that it wandered a little compared to the original tires. It wasn't something I was looking for (ie: not psychological), I was just driving and wondering "Why is it following ruts today?"

I think any time you soften the sidewall it's going to wander more, and 18s are going to be softer yet than 20s.

Never had an issue in any other car, including the C6Z, though. Then again it wandered with the stock tires and this one doesn't, so they improved it. Going to DRs just seemed to undo whatever goodness GM did.

Which Drag Radials are you running?

Funny, as with the roads around here in AZ, the car wanders all over the place chasing ruts on the stock setup. It's a battle at times lol.

No, you're not nuts as I experienced the same thing.

When I first got the car in July I started off running 315/30/18 Hoosiers and they felt a little unsettled going down the track but nothing serious.

A few weeks later I tried a set of 305/35/18 Mickey Thompsons (because they were closer to the stock tire height) and HOLY CRAP, were they freaking scary!

I think I ran the car 5 or 6 times that night and on half of my passes I almost had to lift as I was afraid I was gonna put the car into the wall. I know it had nothing to do with the track as Sonoma is a great track and I trap much higher with my C6 without issue.

I ended up going back to the Hoosiers and things were fine again (for the most part) so I was relieved there wasn't something wrong with the car.

I suspect the fronts are the issue.

Should have gotten the Hoosiers.... LOL going to a track rental tomorrow. Oh well.
