Richard,

Yes you can fit 16" on your 87 SL provided you install 6mm spacers to prevent inside tire wall from rubbing on steering track rod balljoint rubber sleeve due to the 35mm offset. I have them on both my 450 5.0 and 420. You might need to glue a rubber block 7mm to the lock stop bracket on the lower suspension arm to avoid rubbing on the sway bar on full lock. This is only minimal turn circle loss and hardly noticeable. I have 16"X8 with 225X60X16 tires. See pic. With the 6mm spacers you dont need extra long lug bolts, the originals would suffice.
