I am current in the process of trying to get my F-Type R set up for an upcoming track day. I am looking for a source for a set off track wheels and used racing tires. Currently the car has 255/35/20 fronts and 395/30/20 rears.

 

I bet you mean 295/30/20 or 305/30/20 rears.
But I can't help with tyre recommendations, sorry.

 

No such thing. Well, technically you probably could find something like that, but track tires generally last only couple hours of hard track use.

My suggestion is to get a set of Michelin Pilot 4S tires, they are street legal and 95% performance of a dedicated track tire.

Last but not least, don't race on old engine oil or brake fluid.

 

I expect that some of what I learned racing motorcycles applies. With tires, while miles mattered some, the biggest issue was number of heat cycles. The race tires were not fully cured rubber, so were softer. With heat cycles, they'd get harder, and eventually reach an unsafe point. A weekend of racing on a race tire made for a really good street tire though, until I moved to slicks. Nevertheless, SinF's recommendation of the P4S is solid.

 

Coincidently I ran into a guy at cars and caffeine who drives a Pontiac Solstice with an LS conversion he tracks. He buys used track tires. Apparently when a race car qualifies they often take the tires they use in qualifying off and sell them cheap. Granted his car has 15" rims but the things cost him under $50 a tire and they are true race tires. So it is possible, our tire size would likely be problematic though. Anyway I looked at his tires and damned if they didn't look almost brand new. Just a data point.

 

Either Michelin Pilot Sport Cup 2 or the 4S if they'll be driven predominantly on the street. Anything else would honestly be a waste of money.

 

Thanks Guys!

 

Used track tires are a very real thing. They are usually called 'take offs' and often guys with large bank accounts use tires for just one race and then cast them away. They are still plenty good for track days and even more races.

 

You're showing your age. They have made drastic changes in race rubber and heat cycles really aren't a thing anymore. It got to the point where I would get many, many track days out of slicks on the track. I would keep tw sets of wheels, one that I would dedicate for races and another for practice/track days. I would usually switch my race tires over to practice/track day duties after one race weekend (3 sprint races) and then run those same tires for a few track days (I used to be a co-owner of a track day company, so I would go to 30+ track days a year).

That was on my 1000. On my 500, I would change them out of guilt.
