Well, perhaps on paper 235 295 understeer like crazy, but it does not. I somewhat understeer but it is manageable.
The only combination that got me into 1:37 besides RR and R7 is the ADO8R when I was on 265/30/19 front. At that time, I was afraid that 265/35/19 won't fit. But @slicer posts and others convinced me to try the R7 size ls to 265/35/19. It worked ver well.
I liked the ADOR8 the most on the track out of the non slicks.
I love the PS4S 275/30/19 on the road and in the wet on the track.
So a viable non-slick option is the ADO8R in 265/35/19 295/30/19. The the price is almost like the R7, so for the price, I rather get the R7. But I am very curious to give that combination a try.
The RR is not ideal, but factoring the RR price of less than $1000 for a set, and $237 front is very compelling option. And fast.
The RR rears last many track days (so was the R7)
So I rather experiment with the RR since it is the lowest price for almost fastest time.
Last comment about the PS4S. While wonderful tire in the wet and damp surface, in the dry at a 1:38 pace I am peeling the rubber of the tire. So not just wear, but the rubber is too soft.
The ADO8R where impressive at 1:38/37 pace but again I was on -2.5 when I tried them and corded the outside.
In general, I think it is good to be skeptical of anyones findings. At the same time, I have close to 70 track days on the same track, and I am running one of the fastest times on that track given HP and weight. So perhaps it means something. Or not. Who knows.
