i had searched for some pictures a while back with the 10.5 OE rear at all four corners with 275/35 fronts and 295/35 rears. i usually came up empty.

anyway, i just bought that combo so i figured i'd post it up. the PS2's grip like nothing else i've had yet. the 275/35 has a slight stretch on the wheel but will work well when i lower the car a bit more.

steering feel is very nice. i've had not TC/AH issues. i wasn't concerned with that anyway as i usually turn it off, but i forgot a few times and was drive the car HARD with no issues...







if anyone wants a more specific pic just ask...

Awesome - I've been wanting to do the same thing! is your Z stock height?

Do you know the tire diameter on the 275-35-18?

I'm thinking a 285-30-18 would work too?

thanks

Looks good!

Could use more low up front, but everything works well; you won't encounter any issues with AH/TC since you maintained an appropriate F:R ratio

lowered on stock bolts

off the top of my head i don't recall, but i had looked it up on those online tire calculators. a 285/30 would work too, but the pilot PS2 was available in 275/35 and 295/35. i didn't see matched michelin pairs in 285/30 and 295/35

additionally, i ran a square 295/35 setup for a while and it felt very heavy in the steering and VERY twitchy/wandering feeling over the road. i wanted to tray something closer to the OE 265 width.

i didn't seem to have any issues with the 295/35's all around either. i'm as low as the stock bolts will go. i wanted to get pfadt coilovers but with the doors closed i need to find another brand.

ride tech?

rjwz28

Hmmm, maybe it's partially due to the fact that my tires are taller F and R right now

It looks like the fender gap is bigger up front than it is in the rear; maybe that's a part of the visual problem.

Regardless, it turned out great! If I wanted to run stock wheels, that's exactly what I would do: 18s all around to take advantage of the best tires. Are you planning to stuff some big brakes in there now that you have the clearance?

chris__2007

@ rjez28, i'm going to look for stock c6z brakes...

rjwz28

Excellent plan that is exactly what I would do, too

04silverZ06

I think the 18's look good up front too, but other than looks and trying to fit larger brakes are there any other real benefits? Better handling / road feel?

chris__2007

i can't tell a difference driving it I doubt (handle and feel). i wanted the look and ability to stuff bigger brakes. i have (3) sets of C5z06 wheels laying around so I said why not...

04silverZ06

I have a pair of Alcoas which I've thought of doing this with but am concerned about the slight difference in color compared to the Speedlines - might look odd.

rjwz28

More tire options as well 17s are going the way 16s did last decade as far as performance tires go

04silverZ06

How will you lower it more on the front - after market bolts?

chris__2007

coilovers... i am looking at ride tech. i wanted pfadt before the doors closed.

04silverZ06

I may shop for some too. What do coilovers go for on a C5?

Have you thought of LG?

chris__2007

i did... when i last looked it was $2100-$2500

I have been running this tire size setup on my Z06 fro quite some time. Works great and looks even better!
I am lowered as far as possible on stock bolts.

04silverZ06

Any pics of your set up?

More pics of this set up on different cars the better as height difference can have vary and have a visual impact.

thanks

Any of you guys experience rubbing in the front with this setup? On my c6 the rim hits the upper control arm at full lock when on the jack. Anyone else notice anything like this?

To be honest it looks odd because the front wheel is stretched which gives it a rubber band look compared to the back. It gives the illusion that the front rim is larger then the rear because the sidewall differences with the larger rims... Just my opinion...

chris__2007

i agree but that illusion is not because the tire is stretched, it looked the same when i had 295's all around. it seems to be magnified in picture opposed to in person.

i believe the illusion is a result of the front of the car being very light opposed to a rather bulky rear which makes the entire rear wheel look smaller. also, my car is sitting a bit high.

lowered a bit more and lowered evenly should eliminate the illusion. with the stock 17's up front the sidewall of the front tire was taller than the rear, which also looks odd.
