Say hello to Mr.Wankel
iTrader: (7)
The 79 - 80 modesl came with either steelies or waffles. Some special versions also had a rare
AL wheel that looked different from the waffles. Plus wheels didn't happen until the 1981+
models.
To me seeing a nice SA with plus wheels just looks wrong. There's no difference in spacing or
size and even the weights are probably close, so its not a performance issue.
Its personal choice and personally I think waffles rule!

I have 205 Sumitomos on the same stock rims. But unless I have the air pressure topped off, I experience what feels like a "rolling in" of the sidewalls. These stock wheels were only ment to take up to 185's, am I correct? The sidewalls of the 205's seems to bulge out to me. I can't image how 215's would feel like in the corners if you have this same issue.
I have the RB suspension package all around, and still have the watts link. I keep thinking it's the sidewall of the tires, but maybe a panhard bar will help? It's a squishing not so nice feeling around hard cornering.
I never encountered this issue back with the 185 tires.
I have a mostly stock '85 GS with GSL rear.

oh btw, with the GSL rear. Since you're adding disc brakes to a system that is balanced for a drum rear, you may encounter the rears locking up before the fronts. ASK ME HOW I KNOW...
Changing the proportioning valve may also require changing the brake master and lines if the fittings don't match up between the models. I haven't confirmed this. It is still on my list of to do's.

That sounds like it. So if you want performance, get a bigger/wider rim. If you want style, suck it up with "roll" effect. Lol

Waffles - hmmm good

Soft side walls. A real performance tire in that size will have much stiffer side walls.
The Sumo's were never really a performance tire. They just came in the 205 size we
liked and were dirt cheap and performed adequately, even at autocross. So
everyone used them.

They've proven to be acceptable dry-performance "spirited driving" tires if driven within their envelope. They are softer in the sidewall by far compared to the tires I run on the Z... but they also cost about 1/4 as much, too.
Sadly, no longer available.
Past a certain point defined by the suspension design, wider rims & tires reduce handling performance unless you're ready to make extensive modifications to the suspension geometry and steering. You also pay for the larger contact patch in higher rolling resistance and thus required horsepower.
Not to mention the body fitment issues.

well I guess I can add insite here. I also have an early S model 79. but mine came with a 5 speed and the ultra rare almex wheels (which were the best looking stock ones available).
When you switch to the rear disks you WILL need to replace the master cylinder and you can't find prop valves either. so you will most likely be getting an adjustible unit like I did. try your best to save the lines though even though they have the wrong fittings because a $2 fitting is a hell of alot easier than replacing all the lines like I did. you will need new lines from master to prop and a new rear axle line as well.
hope that helps.

Also, good swaybars help a lot with that squishy rolling feeling.
