Think I'm going to need some wider tires
Wish more people posted power #'s and tire specs...
I'm at
324ft tq
401rwhp
@15.8psi
From a mustang dyno
275 35 18 Bridgestone potenzas. Is that too wide or
Not wide enough. Idk... Sorry to thread jack but this thread is seriously lacking numbers and the board is still slow. <3

seriously though I would like an experienced Input on it...

Current rear set up 295/35 BFG Drag Radials with 2 in 1 diff cradle and TII diff. 1st will hold all of 16psi (about 450WHP) without any slippage just rolling into power. 2nd will hold all of about 20psi (a tad over 500WHP) and 3rd and up holds everything. Cars an absolute animal on the street with an unbelievably broad torque and power band.
Previous tires tried were Nitto NT05's and Continental Contact Sports and neither could hold 14psi in 1 or second and 3rd would spin pretty bad at high boost.

If you want traction, go with the smallest tire you can run in the heat range and lower the PSI.
If you want side to side traction go wide.
18's aren't great for straight line traction, smaller diameter wheels are. you run as wide as you can given the heat range is optimal. lower PSI to elongate the contact patch.

Got into a straight line and floored it. At first I noticed a little smother acceleration, then the turbo fully spooled. I lost traction in first gear in a straight line, no shifting. Now that's some power. I'm going to have to go up to the dry lake bed and learn how to handle this beast now...and if I can get some money some wider rims for some wider tires.
My car is my DD and the ultimate goal is to auto-x on weekends. Right now I have Dunlops on there on the stock rims. I've just never had a car lose traction like that before, straight line and not on a shift. I guess it's also because the car is so light. Weight to power ratio and all that. I wonder what my HP is
But your main issue is that DZ101 are not very grippy tires. For autoX/street, I would want Dunlop Direzza ZII, or Bridgestone RE-11A. Maybe Hankook RS3 if wet grip on the street isn't a priority (it should be if you drive the car in the rain!).

Tire make/model is WAY more important than size, but width does still matter (not to the degree most people assume, though) for lateral grip. The best tires for your usage are only going to be available in 225/50-16 max width. You would still get more grip with that size in the tires mentioned above vs. the 255 DZ101s that are on the car now, though.
You *could* go with Bridgestone RE-11 (previous version of RE-11A) which is available in 245/45-16, on the stock wheels, but that might not give any more grip than the latest Extreme Performance tires in 225/50-16.
If you went to 17" wheels you could go to 255/40-17s, which would give you more lateral grip for autoX.
Any case, DZ101 are in a much lower performance category vs. the other tires mentioned above, and aren't even that good in that category.

255/50-16? Kind of a wide tire for stock 16x8" wheels, and 1" larger in diameter than stock (26" vs. 25").

For some reason I thought the DZ101 were the older direzza's the Z1's . LOL
but those aren't terrible either its not like they are all seasons .. No offesne but 90% of the FD's i see have all seasons on . and I'm in FL where all seasons is not even needed .
and like you said a better compound is much more important than width
the R-s3's arent that bad in the rain .. aslong as you drive like you got a N.A 1.3 piston engine....
LOL
ALSO , if you are on a budget I'd Look at the Ferderal RSR's They were on special the other day for a crazy great price . and they are 140 TW .
