I've been running back and forth across florida to the folks to avoid Frances (and now Ivan!) and been running most of the way between 75 and 90+. Just today I had a lowered Jetta pass me lickidy split and I gave the '80 full throttle and hung off his tail until his top speed let him get away. That is until the curves- when he would slow down. I had no need to do so. My '80 wagon has the softer shocks up front and a firm, fully functioning SLS, and new 15 inch 215/60's. It takes the curves like it was on rails and is totally smooth at any speed. My '82 is much quicker to pass others, but has the "sport" shocks (read- stiff shocks) and it drives like a bus with a bad suspension. The stiffer shocks jar the cabin with everysmall bump, and cause the front end to ride higher- and much worse if you ask me, and since I have two wagons with the two setups, I oughta know
Keep the SLS and get soft shocks up front.
