I am not sure if the MAP sensor has to be scaled or anything, so that might have to wait, not sure.

It does. I know that GST and a few other places know the numbers but I've never seen it publicly posted.

I bought one as well. If Shane knows the table settings then that's something you could install in two minutes while the car is on the dyno.

Yea that's what I thought, figured it had to be scaled.

I will wait for the dyno.

Right now I am trying to figure out what to do about rims/tires.

Can't decide between 18x9.5 and 18x10.5 +15. My Advans are no more, had them recycled yesterday, they wouldn't put them on by law, lol. I didn't think they were that bad. So I am accelerating my plans for rims/tires. Came at a good time though, refinanced my house, no mortgage this next month:)

Any suggestions guys? I am planning on running the star specs in either 265 or 275/35 on the RPF1's in either gunmetal or silver haven't decided on color.

Any help would be awesome.

Well, the RPF1's don't come in +22 so you can't get fitment that doesn't require fender rolling. If you're going to roll anyway then you might as well go big, right? Obviously you're going to have worse tire wear from daily driving due to the additional camber that you'll have to run up front but I'm sure you knew that...

[Murlo26]

^I guess I didn't know that...sigh. Maybe i should just do the 10.5's...

I guess the big thing I worry about with that is extra rotating mass, will it be that big of a difference?

The X is already a HOG.

RPF1s DO come in +22, I have some. :) But they are 17x9... Also, RPF1s only come in silver, black, gold and chrome, so if you want a different color you'd have to get them painted.

In my opinion do whatever it takes to use the thinnest spacer in front, if you have to use a spacer at all. I have to use a 10mm spacer in front, added ARP long wheel studs and only had to roll the rear and I'm good. I know you guys have a lot more room to play with, but either way with that much tire I wouldn't think twice about rolling the fenders and just do it anyway.

Looky, new gunmetal:)

I have read to run the +15 offset, only the rear fenders need to be rolled. And then you need to do a pretty big alignment.

I guess I have two questions...it looks like I will have to roll the rears regardless so is there any disadvantage to going with 10.5's? I love the way the look, all nice and meaty, but are they too big? Is the extra rotating mass a big deal?

Secondly, where is a good place to have these mounted, installed and to do the fender rolling? Preferably someone that is a bigger shop so I can do it very soon. I don't want to burn up my expensive winter tires anymore than they already are. I might sell them soon too, to help pay for a winter beater.

The RPF1's are very light so even in a large size it shouldn't matter. I think 10.5 is overkill for 275's but if you like the look then that's fine. I was intending to put 275's on my 9.5" rims.

Yeah, you're going to have to run major camber up front. -3 or more. I've heard that running anything over 275 turns the car into a boat on a road course.

The Alignment Guy (one-person shop) and that expensive Porsche place are the only two that I've heard anything about. It's a great question because I'm going to need corner balancing and a real alignment as well. When I had my coils put on the alignment place was only willing to go -1.5 front and rear. Lame.

Well get on that. Limited edition wheels are nice to have.

A wider wheel simply allows you to properly and safely have a wider tire. I'm running 255s on my 9" wheel, the sidewalls are pretty much flush, will try 265s next. 275 would be pushing it. People run 285s on 10-10.5" wide wheels all day. Bigger wheels and tires are heavier, nothing you can do about it other than get lightweight wheels like RPF1s and lighter tires.

www.thealignmentguy.com - Look no further than Jeff, he is the man. He will align your car well and mount your tires for you for an extremely fair price. You WILL find yourself wanting to offer him more money than he asks for. Why are you going to have to run so much camber?

[Murlo26]

Hmm...here is what i have been looking at, I really like the look. It's Buschurs car.http://www.evoxforums.com/forums/attachment.php?attachmentid=1688&d=1211671015

I like the way it looks and seems to work well, it is the 275/35 tires and 18x10.5's. I think that is what I am going with.

Probably with the gunmetal too, i like darker rims on red cars. What do you guys think for color? I have never seen the gunmetals on a red X or an X in general.

[Murlo26]

Ok so again, lol, There is no reason not to go to the 10.5's since I am going to have to fender roll anyway?

Can jeff do fender rolling?

And I mind as well do 285's then huh?
