295/35/18 on 9.5" wheel

[chrischhorn]

I know a lot of you guys are running the 295/40/18 Hoosiers on the 9.5" on fronts but is there any side effect? Hows the handling? Any sloppy feel at all? I have on order and plan on 275/35/18 on front and 295/35/18 on rears with a 18X9.5 front and 18x10.5 rear but I'd like to go square setup with the 295/35/18's if I can. I still have about a week to change as TireRack won't have my tires in stock till the 19th. If the feel is a little sloppy, is the extra grip worth it? My events are all for Autocross by the way as I'm sure that makes a difference the recommendations.

BTW another perk for me is I work in a tire shop. I can actually remount my tires to rotate as well to get better wear but handling is my main concern. Not tire life.

Thanks all in advance.

i wouldnt run 295 on anything less then 10.5 because of sidewall dynamics under load and contact patch optimization. but im sure plenty of people here have done 295 on 9.5 and will say "its fine"

275 is about the max I'd go!

[chrischhorn]

Well with no other input, I guess I'll stick with my 275/35 on front and 295/35 in the rear.

thats what i would do until you get 10.5 all around, then go 295 square

it'll be a while for that. The WEDs only come in +12 offset for the 10.5 which would probably require more camber then ID like to clear the front not to mention clear brakes. RPF1's probably will be next order in a square setup for but with Hoosiers.

RPF1's don't clear the...ohwait you have base brakes...

the +15 offset does clear the OEM BBK and my AP Racing BBK
it wasn't the case with the +30/38 though

yeah et12 18x10.5 would be really aggressive and prolly rub under track load

how much front camber do you run and what size tire?

The front are 9.5 +15 on 275 tire.

I had to roll the front fender to safely avoid rubbing.
The front camber was like -2.7 (track setup at that time )

What are your rears? I am running SSR Type F's, 19x9.5 up front with a 275 and zero rubbing but at factory height. I didn't know the RPF1's cleared the AP's. found my second set of wheels now I think!

HEY!!! I'm workin on that ok lol. With only autcross out here in Hawaii, a BBK upgrade is on the bottom of my list of things to do. I upgraded the pads to Project MU HC+800 and I think that will be more then enough for just autocross. Also remember our average course is 35 to 45 secs so short courses also.

I run a 305/30 for my rears on my Nismo

I'm also going to be running the RFP1's 18x10.5 +15 all the way around with either the 295/35 or 305/30

The first owner of my Nismo ran 17x9.5's on it, they fit, and barely cleared. You might been able to put a business card between the two. There is some little scuff marks on top the calipers from the rim and caliper deflecting into each other under hard corning and braking.

I cant wait to see the result of 10.5 +15 RPF1 on the 370z.
Because with those 9.5 +15, I had to roll the fender and then getting those 10.5, they will be sticking out even more by 12-13mm !!!

post some good pictureS with that setup as soon as possible
