I have Fikse 8" front rims with a 51mm offset and am having a hard time fitting 245/35 Hoosiers (a 40 series tire is even worse) up front with my 285 rear combo, forcing me to run 225 fronts. I've not had any issues with a MPSC 235/40-18.

Am I the only one who can't run a 245 on a 993 C2?? I'm concerned that if I change the offset of the front rims, I will run into rubbing issues inside the fender liner.

Also, as you can see my car is very low. I'm running 2.2 degrees of negative camber up front.

I sure would appreciate any thoughts. Thanks!

Sorry for the off-topic, but would you PM me or post a larger pic of your avatar? It looks seriously cool.

Thanks,

Mark, I am about to mount 245/35 and 285/30 Hoosiers on my car in the next couple of weeks for the first time. I'm told not to expect any problems, so I'll let you know what happens. I have been running 235/40 MPSCs or Corsas on the front.

Hi mark

i have used 245/40/18 toyo RA-1 on 8 1/2 front wheel with offset approx
52-55mm with approx 1 deg neg camber lowered with PSS9 on my 95 C2

i had some rubbing over bad bumps only on drivers side. i believe rolling fender would have resolved problem

Mark, running 245s up front with no prob, slight rub upper fender well (and full lock), 52mm offset . 3deg camber, What suspension are you running? The 285's will rub on the oil line on 10's with 65mm offset unless you have installed monoball bushings. I used spacers (5mm) prior and rolled the fenders. I opted to 295s and 2 deg camber to moderate the cording of the inside edge (Hoosier affliction). Will confirm the 295's this weekend for wear/rubbing, but on the lift and jacking full load looks good.

Bro - The avatar has been heavily photoshopped and not very well at that. I'll see if I can post a larger shot, but the resolution may not be that great.

Bob - Thank you. You have a C2S and have wider fenders than me. Keep me posted!

Norm - Thank you, too. I think the Toyos are sized differently than the Hoosiers. Your 8.5" versus my 8" is also a factor, too. Hmmm...

Bob - Are you running Hoosiers? How bad is your rub? I have Moton Clubsports with monoballs front and rear.. My rears are a 63mm offset and I have a bit of oil line rubbing with Hoosier 285's. Thank for your help.

65mm , but with a 5mm spacer I had no problems. running mpsc and hoosiers.
245's make a huge diff in the car turn in. My lap times at Summit moved into contention after just one session on the bigger rubber and a very basic lowered suspension. Can't wait to get back with the proper setup. My target is a high 1:23 to 1:24 range ( need a second).

Thanks, Bob. I have way too much understeer and really want the 245's to work.

Mark, only the rear fenders are wider on the "S" models.

Bob,

Silly me, I forgot. Thanks!

you need more negative camber up front. hoosier recommends a minimum of -2.5degrees of camber otherwise you'll get accelerated outside shoulder wear.

do your motons have a 2 sided strut top, i.e. does it have 6 mounting holes? if it does you can flip the top and get more -ve camber. i did this on my 996 and got -3 degrees. i did, however, have to grind away some of the sheet metal for clearance.

Mark,

I have run the 245/35-18 up front with no problems, but then again I ran 265 Pirelli slicks up front two weeks ago without rubbing. BTW, my front fenders are not rolled.

I though you had massive oversteer? What did you do to get so much understeer?

Carlos - I'm going to see if I can dial in more negative camber. Thanks for the tip.

George - Thanks for the info. I couldn't recall if you were running MPSC's or Hoosiers. What's your front offset?

I took care of my high speed oversteer and made the car very forgiving by making a rear bar setting change. However, in some slow speed corners, I feel like I have too much understeer and am wearing out my fronts much faster than the rears.

Mark, I run all kinds of tires. I'm about to try a set of Toyo's just for kicks. It drives my mechanic crazy. Anyway, I was refering to the Hoosiers. I don't think the MPSC come in that size. I actually have the 225/35 and 285/30 Hoosiers on my car right now. I had no problem with the 245/35's with 3 degrees of negative camber.

George, if you go with a set of Toyo's, what size will you be running in the rear? 275/35 or 305/35? I have -2.5 degrees of camber in the back and I am considering the 305.
