POC Race Clinic Video

[Brad Roberts]

For those playing along at home, the white Boxster in front of Tom is Ira from Tarett engineering Ira is in what we call a "GT4" Boxster. Basically it's a HP to weight class with open suspension. We were just trying to get Ira through the school. It was only his second time on the new 255/RR from Toyo. He did "ok" and also passed the school. I should edit down Ira's incar video and post it

I can't find any info on what "GT4 Boxster" means. I'm intrigued. Could you give us a quick rundown on what that entails, please?

Here is a quick run down of the POC GT classes. As Brad mentioned, they are basically a open class of prepared race cars that compete based primarily on weight to horsepower ratio and tire type.

GT Class / D.O.T. approved tires / Non-D.O.T. approved tires (Slicks)
GT1 / less than 6.51 lbs/HP / less than 7.01 lbs/HP
GT2 / 6.51 - 8.50 lbs/HP / 7.01 - 9.00 lbs/HP
GT3 / 8.51 - 11.00 lbs/HP / 9.01 -11.50 lbs/HP
GT4 / 11.01 - 13.50 lbs/HP / 11.51 - 14.00 lbs/HP
GT5 / 13.51 - 16.00 lbs/HP / 14.01 - 16.50 lbs/HP
GT6 / >16.00 lbs/HP / >16.50 lbs/HP

More details can be found on the POC website.

A base 2.5 Boxster Spec would typically run in GT-5. I was pleased that I was able to chase down, catch, and pass ANY GT-4 car.

It was a privilege to have someone of Ira's background in the class. I mean, almost every race car has something from Tarett on it, including mine.

And as long as we're dropping names, it was just as cool to have Connor De Phillippi drop by the December racing clinic and give us some insights and advice.

You meet the coolest people in a Porsche (race car that is).

I'll be running my first set of Toyo RR's this weekend (staggered 235F/255R).
