Got the new rims on the wife's ride last week. We put 17" Simmons OMs on it with 275's up front and 315's out back.

The rears required completely removing the bump stops and hammer in a little of the inside right above the bump stop...at ride height it would clear but thru deep dips it would have rubbed severly....I guess the convertibles are a little different than the coupes in this regard.

 

You have to be a member of the forum to view those photos.... at least that's what the popup says.

What backspace did you get? If possible, I'd like to start adding links and data to the FAQ at the top of the page. Unfortunately a lot of people want top post their pictures, but so far no one that I've asked has replied with the requested info. The idea is to have the FAQ cut down on the "will these fit my car" and "what offset do I need", by linking the examples in the FAQ to actual photos.

 

Fred, since I am a member, I re-hosted them on another site.......here ya go.

 

Thanks for reposting those Joe, I didn't realize you had to be a member to view those.
Fred, the front 17x9 are 43mm offset and the rear 17x11 are 50mm offset.
Seems like when I ordered them, I had requested a 35mm offset on the front as I think that is what the stock WS6 rims are, but the guy at Discount Tire called someone at Simmons and they insisted that 43mm offset would work best and match the rears better so I went with that and am very happy with them.

 

Joe: Thanks for the links.

2QUIK6: They look really good. Generally, I don't like the bolts on the 3-piece wheels, but Simmons seems to do it rather well. Good job.

Any chance you could post a pic from near head on and another from the rear, with the front wheels straight ahead? That would provide a good look at what a 43mm offset (6.7" BS ? ) 17x9 wheel looks like, and where they sit relative to the fender line. Calculations show the outside edge of the wheel will be right where my 17x9.5 49mm OZ Monte Carlos were.

Every data source I have seen shows the stock WS6 wheels at 50mm offset.

 

Yeah, depending onthe offset, the chrome lip may not be visible..in other words the spokes would be on the outside part...I was very worried that they were going to be on these, but luckily they weren't.
I may be mistaken on the offset I was requesting...I guess 50mm makes sense because the 43 offset they suggested was going to put the outside lip further out towards the fender lip and I was concerned about that.

Yes, I can get some more shots and post up on my website sometime this weekend, I'll post back when I get them up there. I meant to get a shot with the front wheels straight cause I figured someone would want that but forgot when I took these.

 

Fred, here's some new pics of the angles yu requested, better quality than the others too I hope.

The fit looks perfect. IMHO, drop the car a bit and it will indeed be perfect.

 

Thanks!!!

Your photos pretty much show the wheels exactly where my calculations say they will be. That's important, because I use the calculations to evaluate a variety of wheel sizes for people, and the more data points and photos I have, the more confidence I have in it.

Its good that you followed up. I'll try and get off my lazy butt and start showing some of the links and data in the FAQ. Wish everyone would take the time to respond like you did.

 

No problem at all. I know I've received a ton of information on this board and others and always try to repay the favors. Thank you personally Fred for all the help you bring to this board and the WS6 board

Oh, if I have time to upload some more pics I took today of the wheel well where I cut and hammered I'll get them up tonight..if not it will be a week cause I'm leaving tomwn in the morn.

 

Here's a pic showing what I had to cut and bang to get the 315's to fit. Bump stops completely removed.
Had to hammer in the inner fender wall lip at the top of the pic and just a small spot just at the front of the well.
Also notice just to the right of the shock, I had to make a vertical cut up a few inches in a "hump" that stuck out..the hump would not hammer down any until Icut the vertical slit up it, then hammered it flat.
On one side, I had a slight rub ..just barely on the outter fender lip, I rolled about 1/4" of it up as well.

I'm surprised you had to take the jounce bumper completely off. I just cut the projecting edge off, and that was enough to keep the rim from catching on it when I jacked the car and the axle went to full drop.

I think keeping the jounce bumper helps prevent damage to the shocks when it prevents them from bottoming out.

I did end up hammering a lot more though, but I was also trying to fit some 28" slicks in there, and it was a challenge.

Stage 1, before the slicks:

See that bump that runs up and down right above the rubber bumper in your pics..it would rub the tire when the axle was at full drop so that is why I had to cut on mine on both sides..even with the rear axle centered w/ the adj panhard.
Maybe a small difference between coupe/ttop cars and convertibles....I have a strange squeek now from that area..can't tell if its inside or outside the car since its right there next to the interior...but since I have to break out the welder to weld up the ends of my SFC that the instructions didn't mention per another post... I'm going to run a bead up that slit I put in there.

I may see if I can weld the bump stops back in there somewhere although it appears that it has never bottomed out on the stop bumper as there was no sign that it had ever contacted the axle.

 

Its hard top figure out why these cars are so much different.... I've seen the exact same set of wheels and tires fit on one car, and then not fit easily on another. Seems like there's a bit of slop in the build tolerances. I guess they never figured on people putting steamroller wheels and tires in the back
