Planted Feet: S30 Rear Suspension Upgrade and More

Filed under: 240z,Maintenance,Performance

This car belongs to the one and only William of William’s Autobody fame.  The 240 came into the shop with a noisy valvetrain so we (Josh) removed the front cover and discovered that the timing chain tensioner had dismantled itself over the last few hundred miles.  Uh oh.  Normally this would result in the chain jumping a tooth or more on one of the gears which would cause terminal engine damage, we happened to get lucky.  Part replaced, Long live the L-series engine!!

Turning our focus towards the rear of the car, we have a slight overhaul in order.  What you see here are a set of T3 (Techno Toy Tuning) fully adjustable rear control arms.  These new pieces are light years ahead of the stock stamped pieces in terms of stiffness and adjustablility.  The perfect alignment is now achievable.  To accompany the control arms and their new bushings are a set of 250lbs/in springs (up from 175lbs) to firm up the rear a bit.

The new rear suspension pieces and and replaced tensioner will help our faithful painter enjoy one of his Z cars to its fullest.  ZOOM ZOOM (He has a Miata as well)  Long Live the Z!!
