Thanks for posting.

One thing I haven't mentioned is my tires. I've had sticky tires on the rear before but when I put them on the front (I think it's a 200 TW tire) it did some sort of undesirable things. First, I could feel all the imperfections in the road surface. Any running low spots/channels, whatever they may be called tends to pull the tires into them. It felt like it really changed the way the car felt when trying to go straight. Also, it really seemed to amplified all the flexing that's possible in the subframe. I really didn't like any of it very much. So we'll see how it feels once I'm done with all these chassis and suspension mods but I may end up going back to a less sticky tire on the front.

Good suspension setup with a proper alignment will cure that. I also run 200 TW all four on A PTFB full comp suspension.

I'm glad to hear that because that's the suspension I'll have when I'm done.

Not sure if it's a correct term or not, but have always heard that 'condition' called 'tramming'.

This also can be elevated when you run 2 different types of tires on the front than the rear. Lots of people mis-match due to trying to use the widest tires possible, and some brands don't make tires in all sizes. Or by running non-radial street stickies in the rear.

I've run drag radials front & rear several times on a couple cars, and did experience some tramming, but it wasn't too bad. But most are a handful in the rain.

I've run summer tires into the cold months and those were like driving on ice when it got cold out.

Since I tend to drive my cars a lot and in different seasons I only run all season tires now, and live with the fact that it will suffer from a stand-still. I generally get about a year out of rear tires, and 2 or so years out of fronts. With drag radials I got half or less than that.

It's best to have a second set of tires if you plan on doing a lot of road courses or autocross, you save money in the long run.

Yes, thank you, tramlining. I couldn't remember the name for it. It seems I did almost everything possible to make it worse. Wider, lower profile tires with a soft compound and no improvements in alignment, suspension or chassis (yet) to help offset any of that.

I guess 'tramming' is a slang of tramlining, and couldn't remember the correct term.

Great link, thanks, I'm going to copy and save that for future reference!

Global West and Speedtech have good recommendations for alignments to follow, FYI.
