A little background. '91 NSX with 445rwhp. Axles and boots repacked 1500 miles ago. BC Racing coilovers on 10/8 Swift Springs F/R. NA2 rear sway bar and Dali Trophy front sway on Carbon6 end links. Stoptech BBK on all four wheels. Tires are Yokohama S Drives 215/40 & 275/35 on Advan Model 5's 17/8 in front and 18/10 n the rear. Rear beam bushing has been replaced with TiDave's non-compliant bearing. Front Steering rack rebuild by Matt Lindsey and realigned to Type R specs in the front.
I sustained a flat rear tire which killed the tire and I replaced with a new S Drive. The old tires only had a couple of thousand miles on them so the stagger from new tire to old is minimal with the rears. I have heat cycled the new tire on over a dozen trips of at least 30 miles each. But ever since replacing this one tire, the rear end wants to step out on hard acceleration. The car doesn't seem as stable at speed either. It seems to want to move the rear of the car to the left (toward the new tire) and the car seems to float a little at high speed.
I've checked the damper settings and they match up. I pulled the wheels off to check the axle nuts. They are torqued correctly and the nuts are staked. The only thing I have noticed is on the passenger side, if I grab the rotor at 3 and 9 o'clock positions and tug in and out, I will get a fairly slight "clunk" in both directions. Nothing on vertical tugging, only on the horizontal. I can't see any movement in the toe link, ball joint or end links while doing this and I can't really identify where this "clunking" sound is coming from.
Westend alignment is 2 1/2 hours away and I don't want to travel that far for an alignment knowing that something will have to be replaced before they can align the car properly. If something is broken/worn/not right, I'd just as soon purchase that part and have them install before we align the car. Oh, previous to the car blowing a tire, there were no issues at all with the way the car handled. It was perfect. I mean it was the best handling, most perfect handling car I've ever owned. So any suggestions out there?
