NEW: Z31 Strut Spacers (Bump Steer Spacers)- US $159
(OUT OF STOCK)
Free Shipping to cont. USA!
Fitment confirmed with 87-89 Turbo front brakes. There may be control arm to rotor clearance issues on some other models and we have yet to confirm. Also known as Bump Steer Spacers or Roll Center Adjusters; we have invested in a single production run of custom made strut spacers for the Z31. Machined from 6061-T6 aircraft aluminum, annodized dark red and including 10.9 replacement metric fasteners, Z31Parts strut spacers are specially designed to fit between the steering knuckle and strut housing. These spacers help correct front steering and suspension geometry when lowering springs are installed, and are a very popular modification for many other cars with similar front suspensions. This kit will be an absolute must-have for those drivers looking to get the best performance out of their suspension with a lower than stock ride height.

THE WAIT IS OVER!
Finally; a truly high-performance drop-in spring for the Z31 300ZX. Our custom-wound "Z3R" springs feature three lowering choices for each front and rear pair of springs. With high quality custom wound coil springs in rates tested and selected for amazing performance both in autocross and on-track, ride quality is still relatively comfortable..
Proper damper selection: Your Z31's ride will be firmer regardless, but correct damper selection will make your Z31 handle like you have never imagined. We do not sell, but do recommend using Bilstein (~$450), Tokico Illumina 5-way (~$480) or Koni Sport (~$600) shocks with Z3R springs.
Rear camber: Generally rear camber will be acceptable with the type 1 springs, while it should be corrected with type 2 and 3 rear springs for best performance. All alignment and any other related vehicle suspension settings are solely the responsibility of the customer.
New rear spring isolators are also highly recommended.
Spring Selection: You may select a different rear and front pair of springs. Keeping the same type for front and rear will generally give the vehicle stance most customers desire, as Z31's do tend to ride slightly lower in back with stock springs.
These coil springs are custom wound in the USA!
Z31 Race (Z3R) Coil Spring Sets
Because the Z3R springs are a relatively high-cost item and I lack the capital to maintain large amounts of inventory, these springs are produced and sold in small batches Z3R springs currently in stock as of the last update are listed below. Subject to change, quantities are not automatically updated! Please send me an e-mail if you would like to reserve a set.
Please be aware that lowering springs have a shorter free length and the rear springs may require machining shocks shafts or the use of some kind of additional retention mechanism should the suspension frequently be in full rebound (unloaded) while the vehicle is moving.

Z31 "Basic" Rear Camber Template Kit - US $14
(IN STOCK)
Free Shipping to cont. USA!
Due to its design, the rear semi-trailing arm suspension on Z31's has a lot of camber change built in. For this reason, negative camber can become excessive when the rear ride height is lowered more than about .5". This camber kit is the most inexpensive on the market, as it is simply a template to help you drill a new outer control arm mounting mount lower than the original which usually adds approximately +1.5 degrees of camber to the rear wheels.
Can also be ordered with 1 degree of correction by special request.
