Default Bugeye 17x9 et42 Handling?

I'm thinking of 17x9 either Rota DPT or Mach V Awesome. I'm leaning towards the latter for brake cooling. I want an opinion on how its going to handle compared to a 17x8 before pulling the trigger. Also need tire suggestions please. I'm willing to roll but not pull and I do NOT plan to slam the car (at least an inch of gap expected).

Other supporting mods:
QRack 11.5:1
Tarmac 2 Coilovers (500F/400R)
Ground Control Front Camber plates, Cusco rear camber plates
Whiteline F/R 24mm adjustable
Brembo's F/R with DBA 4000 rotors, stainless lines

Primary use - HPDE

Thanks!

I run DPTs in that size. Tires are 255/40-17. I've done some very minor rolling in the rear. I've got about the same size fender gap and my spring rates are 400/400. I also run ~8mm spacers up front.

During normal daily and spirited driving I have NO issues. Once in a while (very seldom), I'll find a BIG bump or pothole that compresses one of the rears enough to scrape a little strip of rubber off the tire.

IMO, definitely get the 17x9. You'll have no issues if you run a 245/40 and/or actually roll your rear fenders all the way.


EDIT: I can't give a direct comparison in handling to a 17x8, but just remember: any time you increase track (width), you effectively increase roll stiffness. You might have to put up with a bit more bump steer, but that's a worthwhile trade, IMO!

EDIT 2: For tires, assuming you want streetable ones (not slicks), I think the Potenza RE-11, Ventus R-S3, Ecsta XS, and Direzza Z1 Star Spec are still the best summer tires around. Star Specs seem to be dominating my local autocross, and are almost as good as RE-11 for WAY LESS MONEY. I've owned the Star Specs and the Ventus R-S3; both are great tires, but I think the Star Specs had a slightly more solid feel (less squirmy).

the 17x9 +42 is likely the best size with a 245/40

a 255/40 may be problematic

the 595rs-r in 235/40 may be a good way to go if ya want to drop the gearing a lil

Thanks for the feedback guys. I think I'll start off with the 245's then. I know the Mach V's clear Brembo without a spacer. Not sure about DPT?

I went from a 17x8 rota with a 235/40 RS2 to the 17x9 Mach V with a 245/40 AD-08. Feel and over all grip was noticeably improved. Turn in was quicker, the ride was better, the tire is quieter, and noticeable less tramlining.
I did have to roll the rear, they would rub on large bumps.

OK...... Ordered the Mach V Awesomes. Now I need the 245s. Primary use is HPDE so who has the grippiest? Dunlop Direzza Z1 Star Specs? Hankook Ventura RS2? Others?

Direzzas and RS3 would be my 2 preferred choices. Kumho XS its a good tire if you can find a good deal. Falkens have fallen behind. Yoko I don't think price difference its worth it. RE11 are great but dunlops and rs3 are way cheaper offering same grip.

I run the same wheels with 245/40 R17 RS3's and have found them to be a great tyre, I haven't tried the star specs though.

Do it. You won't find a better tire for the money.
