I have that size combo with CT-R's.

The taller tires will jack up the rear end, and you will want to get lowering springs, otherwise the high center of gravity will affect handling.

WIth the less sidewall up front (changing from stock 17's) the front end turned in faster with less rollover, so it felt like it turned a little sharper.

With the taller sidewall in the back, it provided more flex for launches, much better traction, and got ride of a lot of wheel gap.

The panhard bar is for recentering your rear axle. You may need it, you may not. Stock, my car was centered, with Roush rear springs, it kicked the drivers side tire out 3/16".

The lowering springs also through out my pinion angle, getting it pretty much to zero, so adjustable LCA's moved the axle back and lowered the pinion angle back down, but, now the rear of the tires have rubbed on the inside of the fender, so I'll have to install the adjustable UCA to get the axle pulled back forward with the right pinion angle.

I love the look though, and glad I went with it, and was planning on getting adjustable LCAs, UCA, and panhard bar anyway.

1. I agree
2. I didn't have to use spacers, I just bolted them right up and havnt had a problem. My rims are from American Muscle.

3. I've nailed the brakes pretty hard on the race track but have yet to have the abs come on. I think some paramaters can be changed in the tune to allow for different tire sizes front/rear to adjust for that.

I want to thank everbody again for all their feedback. I'm ready to go ahead and order the wheels and tires (255/45/18 & 295/45/18). However, now that I've gotten to this point, it turns out that American Muscle is out of stock on the 18x9 deep dish bullitts (anthracite). I called them and they said that the wheels are on national backorder and they are not accepting any orders for them at this time (althogh it looked as if I could actually place an order for them online). I was also told that they don't expect any in until sometime this summer. I don't know if I should go ahead and order the 18x10's now and order the 18x9's later or just wait and not order anything until the 18x9's come in later (much later). I'd hate to wait to order the 18x10 only to find out that they end up being out of stock when the 18x9's eventually come in. On the other had I'd hate to order the 18x10's and then find out that something else happens and that I can't get the 18x9's later for some reaon and end up not being able to get matching front wheels?

Discount Tire Direct online man - that's how I got my set-up

chrome DD 18 by 9 fronts, 18 by 10 rears with tires mounted and balanced for free - AND a lot more selction of tires that AM gives you...

Give it a shot

Been there, done that! My fronts showed up 2 months before the rears did. I had to go out to the garage every week, take them out of the boxes to reassure myself that one day, I'd have the 18x10's for the rear. I was at the tire shop 2 days after they showed up However they never told me that they were on "national backorder" though. That sounds pretty discouraging. I'd definitely check the link Burke0011 mentioned

Thanks for the tip! I was planning on purchasing the tires from Discount Tire Direct anway. I looked on their site, and I found deep dish chrome bullitts in 18x10, but no 18x9, and no anthracite. If anyone has a direct link, or another site, I'd appreciate it. Otherwise I'll probably just place the order with American Muscle and play the waiting game. I will be like ordering my car all over again, except with no ERL to call every day to check on my order.

Why not 18x10s? A 295 on a 9" wheel is pushing it some, anyway.

KB9KHM

I'm planning 18x9 with 255/45/18's for the front, and 18x10 with 295/45/18's for the back. American Muscle has the 18x10's in stock, but the 18x9's are on 'national backorder'.

I say order the 10's now and wait on the 9's...

I doubt they will stop making them since they are so popular.... it's possible that some Chinese New Year thing held up production during feb and thats why they dont have any in stock.

(seriously... no joke... in side of the rims have a sticker that says "made in china")

KB9KHM

I went ahead and placed the order on-line. The website didn't prevent me from ordering the 18x9's, so I just included those in the order. I'll play dumb and call them up in a couple of weeks and ask what's up with the 18x9's that I ordered.

I've got a set of Corsa axle-backs coming in a few days, so I'll have something to distract me from waiting on the wheels ... well for a while anyway.

Sure, basically I wanted to polish the calipers anyways so when I got done I threw the wheels back on without a spacer and they fit. It was very close before anyways. I thought polished calipers with chrome wheels would look good. Used a dremel and a little hand sander.

StangFreak

The 3% rule has to do with the braking and the possibility of throwing off the abs system. Doesn't mean it will, just that there is a possibility.

Thanks.................good info!

Here's a picture of mine 265/40/18's on a stock rim. Not much of a sidewall issue.
