[Fot] Race tires

[Scott Janzen]

I currently run the Speedsters and used to run the R888Rs.  I find the performance new to be pretty similar.  However, the R888R tends to get loose and greasy when hot, 2/3 of the way through a race in the summer, where the Speedster holds up better for the duration.  Speedsters wear faster,  and cost more.  Toyos wear like iron, but after 10-12 heat cycles they are not as good.  I used to have the Toyos shaved, no need to do that with the Speedsters.
Just my 2 cents - running 205/60-13s on the GT6. 
Can’t find good info on the R7 compound.  Someone could call Hoosier and ask.  
TDRs are a bias ply tire and don’t like negative camber (according to the Hoosier engineers) where the radial Speedster works well with it.  I run almost 3 degrees negative front and rear.  Lots of effort to switch between the two tires and compare.  Looking at cars with TDRs on the track, they tend to “drift” more.  Fun to watch, and seem to be quick.

I believe Speedsters are the same compound as the , banned by most groups, R7 pseudo slicks. I like the Hoosier TDRs. They last longer and are very predictable. I have a set of the Proxies but, just me, I didn't know when they were going to lose grip. I need some skid pad time with them, and a camber change according to Hoosier to feel comfortable. I do use them for rain tires and off track parade laps. 
A good friend of mine loves his Proxies on his MGB, but I consistently out handle him in the corners.
