I have run these tires on a Fiero track car and a Triumph Spitfire track car. I also have road versions of both of those cars, so I know the difference these tires make. They are fantastic track car tires. They grip hard and warm up fairly quick (the spitfire is a really light car, so thats a good thing). Bolt a set of these to your car and have a great time at an autocross. Don't buy these as your only set to drive everywhere. They wear pretty quickly, to be expected. They shouldn't be left on the car under 40 degrees. Also, if you are new to the chassis you are bringing to a track; these will hide a lot of suspension flaws. I would recommend learning on a normal radial and moving up to these if you want to hone your skills with your car. I did not with the Fiero and I regretted it. So I sold the Fiero and built a Spitfire because I am way more familiar with that chassis and its handling characteristics.

I love these tires! They do what they're supposed to do GRIP! I took them on a road course with me & my car felt rly planted on the ground! Also took them on the drag strip & did not spin whatsoever! I did a lil burnout & these tires definitely stuck!

Can not go wrong with these tires !

Running a car with over 850+ ft-lbs of torque the tires lasted me 4-5 months of daily driving from the end of winter (February) till June of spirited driving. When first driving, they sounded like a fighter jet but I got used to it. The tires take a while to warm up w/ a stiff sidewall for good handling. In cold or rainy conditions if you drive like a sensible person they do pretty well. On wet concrete you can feel the car dance & during heavy rain.

Great handling tires very sticky noisy but that's OK I'm a driver and that's what I like

Love the tires and design gives a good look to my cat and grip and handle well

Wear is quick . Only one summer no burn outs.

I was told by the shop who did the build on my 2016 c7 z51 that the Toyo R88R tire is the only way to go with the amount of RWHP. My vette has 719RWHP and these r88rs have held up as best as anyone could expect to the rough highways and my heavy foot. Thanks

If you're looking at this tire for your performance car or truck, go ahead and get them! They grip corners like you're on rails, and launch traction is greatly improved over stock.
