If the car has shocks that work, and you will drive it hard enough to use full travel, it does not matter what the ride height is when it is (hard) parked. You will eventually bottom it out and whatever is going to rub, will rub.

I do agree with you, that if you drive the car hard enough, you can make anything rub. I just wanted to get a reference for street driving.

I don't understand why people are still asking if 245's will fit on 15x9" on an NA. I've already proven that they do with 245 RC1's at proper (949 Setup Guide) ride height... in a race environment where full travel is used...

Maybe because you only posted one photo and you weren't even sure if they were 15x9 w/ 245. Also, no ride height info was given, I follow 949's setup guide as well but you can't assume everyone does, or should I since this is MT?

I believe this picture is 245 Maxxis on 15x9. Back fenders are rolled with maybe a tiny pull, front fenders are rolled and pulled.

Not exactly. Some wheel/tire combinations will not rub regardless of what you do.

When we check for wheel tire clearance we put the car together without the springs. We can then cycle the suspension through its full bump travel crushing the bump stops, check full steering lock and see if anything is touching. We then put the springs back in, align it and then basically jump the car while turning at Max G. This flexes control arms and other suspension pieces while deflecting the bushings enough to move a tire that was maybe just close on the rack with no springs into hard contact with something when it's pounded over a race track kerb.

Many of the wheels that we offer with the standard tire sizes that go with them are what we call Race Fitments. That means that under normal use on track they don't rub anywhere but they might rub slightly at full lock when you're parking the car or maybe turning into a steep driveway.

I was only referring to the 245 :P

But good info, thank you emilio

Even if the photo wasn't. I've done it. Also like Emilio said, static ride height is not very meaningful. They clear all the way to the bump stops.

I went back to double check what tires I was running that weekend and those are indeed 245 RC1's on 15x9" wheels. Advanti S1's.

Der_Idiot 04-21-2016 02:30 AM

Standard 949 dual-duty alignment, riding at 4.25 and 4.5 at the pinch weld iirc.

Drove the car in a downpour tonight at 70mph, tires held their ground and laughed at it when I stepped on the gas. At least until I got into double digit boost levels. I think I'm in love.

It's supposed to rain here tonight and tomorrow - I put the comp2's back on just in case. Your post gives me hope.

I went to another local autox event and I'm really in LOVE with these tires.
They are extremely easy to predict at limits.

I actually did pretty well on today's event thanks to the new Maxxis 245s/15x10 6UL setup :skid:

Looks hooked up.

I have to say that is an incredibly dangerous course. Whoever designed that course does not understand vehicle Dynamics or the way a car will Spin and the way the driver will correct if there's an error. Two separate spots where a basic spin would have taken out bystanders. Yikes.

DeerHunter 04-24-2016 12:45 AM

How'd the GT4 do, comparitively?

Seemed like local PCA doesn't have anyone that actively autocrosses.
Yeah course layout was pretty bad/dangerous compared to the local region SCCA.

I think I was about 2 seconds faster than the fastest Porsche on this event.
But to be fair, this region PCA doesn't seem very active on autox because I'm not anywhere near the fastest in my local region SCCA.

kmvguy 04-25-2016 11:02 AM

Pfft...
Sorry, I lied about the time. :BSmeter:

PCA just posted the time for the autox and I was only .6 seconds faster than the fastest Porsche that day.
Fastest Porsche was the GT4. GT4 ran 37.4

just clarifying....

Yeah, but...... will the 245 VR-1s with 15x9s fit on a NA?!?

:giggle:

thumpetto007 04-25-2016 04:03 PM

The real question is...

Will it blend?

rwyatt365 04-25-2016 04:07 PM

Did an autocross this weekend past with the VR-1's on Advanti 15x9's. These tires are freakin' AWESOME!

Tons of grip. Handled transitions better than I could. Easy to predict at breakaway. I under-drove them most of the day 'cause I wasn't used to a tire like this. I was 3.5 seconds off of FTD for the stock classes and I could have shaved off another 2 sec if I didn't drive like a pu**y. These tires are AMAZING!

I can't wait for the next event and start driving like a MAN!!

Did ~6 sessions on them at SMMR this weekend. 245/40 VR-1 on 15x10 6UL, 600/350 MSM Bilsteins, full-weight NB2, 200whp. Initial impressions are all thumbs up. They are very forgiving, similar to an RC-1 in that respect. They tolerate lots and lots of slip angle, and breakaway is very progressive. Lots of audible feedback when you exceed the limit. Optimal pressure seems to be 1-2psi higher than a 225/15x9 RC-1 combo. Wear is minimal, far better than the RE71R/RivalS/V720 group. I did not get a chance to do a consistent A-B test with the 225 Rival S since I was making other tweaks to the car and picking up big chunks of time in each session.
