I was talking to the guys running 245/255's last year in the heat and they were as fast as the skinny "one lap wonder" times...I just got some rivals and the 225 is almost 235 wide...

What about testing the TRD intake with an ecutek tune to compare with TRD intake without an ecutek tune. I would be very interested in seeing what numbers it will put up and if with a tune it will give better numbers than the other intakes around

I have no clue what HPDE students don't say out a whole session, so for these types of people, I am personally recommending a larger tire such as a 255/245 for HPDE students due to it's larger heat capacity. It might not be as fast, but in an HPDE environment, we shouldn't be worried about lap times at all. It was easy to drive from lap 1 and didn't get greasy. I found it to be most consistent and lead to the smallest delta between lap times this past weekend.

Our 225 A6s fell off after 4 or 5 laps in 60 degree weather - they were quite old and had many track records on them in TTC and TTB trim. Even after a rolling cool down lap, all subsequent fast laps were not as fast as lap 3/4. It was impossible to bring them back down to a good temp without bringing the car off the track (which is to be expected).

For a newer, less experienced driver, I'd say it's better to over tire and be able to drive consistent, safe, fast laps, lap after lap, so I'd go with a 245 or 255.

For more experienced drivers that are okay with a looser car, a 225 or 235 may be the way to go because you'll put more of an emphasis on lap times.

We will be testing the 225 vs 255 theory out in the next few weeks using brand new Bridgestone RE-11A and running them in back to back sessions at Gingerman.
By that logic, newbie shouldn't drive on the stock tire because it's the "loosest".

You're not changing the grip balance with smaller tires, just reducing grip period all around. If skinnier tires are looser, then that's a result of your driving style...

I was referring more to the car being looser from greasy tires later on in the session...255s can stay out longer and stay consistent, and not at the newbie level either - I was taking more about driver with some track days under their belt but that are still figuring out a lot on track.

Newbies can get by with far less because they don't tax the car as much in general. It's the drivers that ate starting to get their confidence up but still aren't out there running in open passing groups or competing that would benefit from a 245 or 255 set up in my eyes. MANY twin owners fall into tho category. A lot of owners aren't as lucky a we are and dont get to track multiple times a month or haven't yet developed the skills that we are fortunate enough to have. It's important for us to remember this (which I know you know mike ).

I've never seen one optimal set up for any vehicle that work perfect for all driving styles and skill levels. To try and pretend there is one is ludicrous in my opinion.

With regards to tires: More heat capacity = longer session with consistent laps = more time to focus on forming good driving habits.

I completely agree that a 245/255 is MUCH easier to drive. The car is far more forgiving, and the sheer amount of grip makes the car literally turn like a go kart. It lets those intermediate level drivers get used to the feeling of staying WOT through turns, and powering out without having to fear the rear stepping out.

I've discussed with the rest of the CSG team about running larger tires simply for heat capacity. I've been frustrated for a long time with this "one lap wonder" business. It doesn't help that my driving style tends to cook the tires rather quickly.

I'd like to see the real world difference between a LIGHT 17" setup and a LIGHT 18" setup. Something like a 17-lb 18" wheel vs a 15-16 lb 17" wheel with the same tire width and diameter, just different sidewall height.

Know any WRX owners with 18" RPF1 or Volks?

I'm probably going to swap back to the 245's next time around as these 225's are going off too quick for me. I think we have a similar style where we overdrive the tires.
