RUSSJZ-ZED Posted February 3, 2007 Share Posted February 3, 2007 I have a problem with the tyres (just)catching on the outer edge of the rubber (and bending) the bottom of the front guard when on lock. -17 X8 inch wheels, 235X45 rubber, The control arm rubbers are about to be replaced with urethane,will the new urethane bring the arms back in line(if this is problem,original 30+year old bushes) or do any problems arise if I reverse the bushes and put the longer bush side to the front, to create the small clearance I need?

blueovalz Posted February 3, 2007 Share Posted February 3, 2007 I believe the rubber portion is installed on the forward position (sleeve extends further out the rear end of the bushing) in the OEM position. Swapping ends would cause the strut to be moved forward as the arm is pivoted along the T/C rod mounting position when the inner portion of the control arm is moved rearward. It would be an extremely small forward movement, but it would not move it rearward. Also, the polyurethane bushings allow very little misalignment, and moving the bushing rearward, while still maintaining the OEM length T/C rod would cause some misalignment on this poly bushing causing some adverse effects on assembly. Now, swapping the bushing, AND perhaps shaving the rubber biscuits (and shortening the inner sleeve) on the T/C rod may, MAY, get you some needed clearance, but then you've reduced the caster. One thing always affects another thing, which always affects something else. Quote Link to comment Share on other sites More sharing options...
260DET Posted February 4, 2007 Share Posted February 4, 2007 Massaging the guard may be an option, done carefully the paint should not be damaged. Use a curved piece of wood levering off the tyre and roll it along the guard where its hitting. Pics of Z? Quote Link to comment Share on other sites More sharing options...
RUSSJZ-ZED Posted February 10, 2007 Author Share Posted February 10, 2007 Massaging, or cutting are not options, I have a Zenon front dam and any "tweeking" of the guard will have to follow into the dam, right on the junction of the guard and dam is the problem point. The rear edge is the thickest part of the Zenon, it would deform at speed with the edge cut back. Think smaller diameter tyres may be the way to go, don't need much, only touching on left wheel on full R/H lock.Pic of wheel in straight ahead position in my gallery on classicz.com(same user name) Quote Link to comment Share on other sites More sharing options...
260DET Posted February 10, 2007 Share Posted February 10, 2007 Had the same problem at the same point with my S30 but it had a fair bit of caster at the time, it had adjustable tension rods so easily fixed. Quote Link to comment Share on other sites More sharing options...
RUSSJZ-ZED Posted February 10, 2007 Author Share Posted February 10, 2007 the adjustables would fix it, but car is being built for cruising,bit of a waste,never use them once the scuff was adjusted out.I'll try tyres. How is your 130 2 seater going? they are 1000% better looking than the 4 seaters Nissan Australia decided we should have.( even the Z31s look good without the back seat.shame we didn't get them as well.- One good thing about the 350Z, Nissan australia didn't get the chance/choice to screw it up) Quote Link to comment Share on other sites More sharing options...
