Okay, I just spend almost an hour on the "post your caddy pics" thread looking for this info, and only found one person that had posted their ride with 18" OEM wheels. Who's got em and what size tires are you using?
erm, as long as the wheel is the correct offset and/or unless the 18" wheel weighs 100lbs more than the stock 16 or 17" unit theres pretty much no way a wheel alone can do any harm to the suspension at all. also, there have been quite a few vehicles on here that have 18" wheels on them.
regarding wheel size, a 235/50/18 is a direct replacement size vs the stock 235/50/16. a close size would be 255/45/18. i dont know how much clearance there is for a tire that wide though. it would probably fit.

I wouldnt say bigger wheels are less common, you just have to ask the right people. And yeah with the correct offset your car will never suffer from suspension issues. Im not sure about the super big rims 22" and up, but I've had 20" rims on most of my cars and never had any suspension or driveability issues. Just make sure u get a rim with the correct offset, lug pattern size and dont go beyond a 8.5" wide rim.
Nothing wrong with the right set of 18's with a late Seville. As stated, stay within the OEM outer diameter specs for the tire, be careful of section width (how fat is that tire ?) and watch bolt pattern (115 x 5) to preclude incorrect stress on the hub.
Go to www.wheelcollision.com and get to Cadillac wheels, then look at some of the '03 - '04 - '05 Deville and CTS wheels. If you click on the little pic next to the wheel description you'll get a better picture of what you're looking at. Remember what car you're trying to "upgrade": a Seville, not a ricer. Two-tones, rivets, weird knife blades, giant flat 5-spokes - all look horrible on the car. Anything in an 18" is going to weigh a pound or so more than the stock 16's or 17's, but the resulting tire will weigh correspondingly less, so its a wash. As long as the tire outer diameter is within 0.25" of original it will have absolutely no effect on braking effectiveness or speedo/computer settings, and may just give you a tad better cornering ability due to less sidewall height.
There is a picture posted around here of a member who has a Crimson '00 STS with 18" '05+ STS performance wheels. Looks damn sexy. The '05+ STS 17" wheels look good too, though I prefer the performance package wheels.
Yes, that's exactly what I'm going to go with. They are OEM STS/CTS sport wheels with 40mm offset, so not worried about the suspension issues.
I actually just picked these up off of ebay for 7 and some change. They came with 225/50/18 Potenza tires, and that's the brand I'm running on my mom's car, so not too dissapointed there. Have been spending my free time looking for the rim that is closest to the STSi original stock photo that is floating around. These are 12 spoke and the photo was 10, but I think the look will be the same. Couple that with the new front facia I just ordered from Mando, and we're in business baby!
