I did my first event on street tires and I regreted it after two 15-minute rounds. Slow and sliding in corners with the stock weight and overheating after 2-3 laps (5 km circuit).
Not saying that the driver mod is not important, it just depends on the driver's level of skills, experience and confidence. Even simracing helps with this 'mod'

Can't wait to try my Z on the Nordschleife in September. This will verify for sure if I need to invest more in my driver mod Hopefully I won't end up in a barrier!

 

I don't know how all you guys are over heating. It was 95 degrees, humid, and my temp was fine the whole time.

Definitely would recommend the RS3. I really had to push it to get them to even squeal going around the corners. Real sticky tire for stockish power

 

That's actually the point of why I tell many of my newer students not to get stickier tires.

Most times tires offer the most G forces at about 10% slip angle. if you have a tire with a higher threshold the speed needed to get that slip is much higher. They also don't communicate to you nearly as well. In most DOT tires the difference between a slip and a slide is the sound (small squeal vs a howl).

Also, in most DOT tires the break loose threshold is pretty wide, on R-Compounds and slicks, it's a pretty fine line.

Then there is the points of entry speed, rotation (either lift or throttle), speed bleed off, and exit throttle. It's much harder to teach those on sticky tires.

Just my $.02 worth.

 

Ummm, yes.... and therein the point of driving school/driver mod.

School and/or seat time. Preferably both.

Street tires. Marty said it very well. (Great $.02, Marty!) My first class waaaaay back when was taught on street sedans wearing RE-TREADED street tires. (Bandags) You learn pretty quickly exactly what the car is doing through the feel and SOUND that the tires made.

Only after you learned how to interpret that did we get to move on to the Zs and eventually the FFs.

I've run everything from pure street tires to DOT-Rs to full-soft baldies (variety of cars). Most fun - not necessarily from a grip perspective - are the street tires due to the communication and live-on-center response.

On sim racing, well, I'm much too old to have done that in my "formative years" (Laff!) and I have little doubt there's benefits to be had (Hey, pro racers all the way up to Hamilton and Vettel all use it to get track familiarization!) but I'm still a little dubious of anything that you can crash and say, "Oh, well, hit < reset >...."

 

If you only have a few seasons or track days under your belt, you are a novice. Sorry to say but no amount of mods will make up for the lack of track experience. You may think your gods gift to track driving. We ALL have so much more to learn. Spend your money on as much seat time as possible. Driver mod is the way to go.
