Hello. I'm in the process of replacing my front struts. It's a 2003 XI wagon. I just realized I do indeed already have the reinforcement plates. However I do not have the spacer plates mentioned above, part number 31306779671. I did have the large 14 mm spacer on the rear springs. That made me think I did have the rough road package. Am I supposed to have this spacer plate? Does anyone else have it? By the way one day each to drill out both snapped pinch bolts. Auto parts store spring compressor wouldn't fit. But one step at a time, almost done. Had the springs compressed at a shop.

My 330xi Suspension Set Up

In case other owners would like to see what the Koni adjustable sport shocks and struts with the H&R spring set up looks like...It is a rougher ride however my car has little body roll in the corners. I love this set up. I love it even more with a smooth, open mountain road!

I have ASA AR1 18x8 and 18x9 staggered wheels. And I have 245/40/18 Continental Extreme Contact DSWs on the front and the same tires but 265/35/18 on the rears.

OK, that makes sense. Your front tires are over sized at 25.7 inches & your rear tires are over sized at 25.3 inches. Running over sized tires has many downfalls & I'd never recommend those sizes, but since the fronts are as big as they are, they do help fill the front wheel well a little better.

+1 on that, and I've never heard if any benefits of running a staggered setup on an xi.What i have heard is that you should stick with a square setup on an xi

The fronts are oversized by 2.6% and the rears by .9%. The OE tire diameter is about 25.1 inches and the 265s are at 25.3 inches amd the 245s are at 25.7. And with even wear those diameters will decrease overtime. However, they are still under a 3% difference and I get about 25mpg city and highway.

The offset is +42 on the front and +45 on the rear I think? I do agree for the xi a staggered set up is not the way to go. The wheels were a graduation gift from my parents and they didnt realize the wheels were not a square set up. So I originally did 255/35/18 all around but they had to squeeze onto the front wheels. However, when I switched to the 265/35/18 and 245/40/18 they fit the wheels perfectly. The fronts didnt rub at all and the rears only grazed the inner sidewall by a hair so I filed down some on the inner wall by a few millimeters and no more rubbing.

I am looking into doing 245/35/18 all the way around or 255/35/18. But, I don't think the 255s will fit on the front without some mods so I might do the 245s.

Running an oversized tire is performance robbing for one and two you are putting undue stress on the drivetrain of the car.

Get the correct tire sizes on the car.

Excuse me sir, you do not know everything I have done to my car. Secondly, my car is performing exceptionally well. And may I ask what you are running on your BMW? Also, yes the larger tires do take a little off of my potential in mpg and acceleration; they do, however, perform fantastically around corners. Even having a staggered set up, my car holds through a corner with little understeer.

Thanks for the quick response! That doesn't sound too bad, i really don't have much to any personal experience actually messing around with different tire sizes though...the wheels look good though!

Thank you, and they do look good and give the car a look similar to the new M3. All in all, I would prefer a square setup with a smaller diameter to regain some acceleration and reduce the weight. The set up I have looks good and handles surprisingly well, but I think it is more than the car needs.

Seriously, putting the wrong size tires on an Xi is not the way to go.


You'll figure it out in due time....

I apologize to say Rob43, it has already been quite awhile and my car has no issues. I constantly maintain and upkeep my car. The drivetrain is handling the extra strain just fine. I do understand the cons of having larger tires. I am also searching for a new setup of wheels and tires if you hadn't already read. My car isn't a race car, however, it was my temporary autocross car. Now I am making good progress on a car that will be meant for only racing.

You don't need to apologize, you can do whatever you want with your car.

Drop the attitude.

How do you even know the drive train is taking the extra strain just fine? When your TC or transmission packs up we can reference this post and know why.

Im running a square 18x8 setup with Michelin PSS 225/40/18. I run 17's(225/45/17 = 24.97d) as my winter tire.

I know the car's performance is being robbed because I have a friend of mine that is driving around with squared 225/45/18. The diameter of his tires are 26.1 and mine are 25.2. Going between the 2 cars the acceleration difference is pretty noticeable.
