for a long time people have been making various forms of aftermarket syty suspensions and each persons design has had its advantages and disadvantages. we are hoping to redesign the syty suspension again so that it can be installed with basic hand tools on a saturday and fit the way its susposed to, with minimal modification to the truck itself.

we have several ideas for improving on the errors of the various other kits offered, and hope to improve ride quality, handling, fit and finish, and instalation issues.

1. we will attempt spring spacers, for double stacking 2 spring rates, for a progressive rate spring typical of the factory suspensions on newer sports cars with beehive shaped spring/strut designs. we tried our best to get spring stackers from various aftermarket sources but no one seemed to make them in the sizes we needed for this suspension. the standard stuff just wont work for the clearances we need.

2. most people mount the shocks upside down, so the small end is at the top, to avoid the issue of contacting the upper mount with the spring cup. this in turn requires that the larger end of the shock be mounted at the bottom where the space between the axel and steering linkage is limited. it also requires shimming and spacing the shock awkwardly so its not truely perpendicular in the mounts, and often cutting away portions of the bushing on the shocks. our plan is to manufacture spring extensions for spacing the spring cup down lower on the shock so the cup and spring do not contact the upper shock mount. this will allow us to mount the shock "right side up" and avoid any fitment issues between the steering linkage and axel. this will also allow for a bolt in spacing and eliminate the need to hack portions of the bushing off the shock to get the correct allignment.

3. when coilovers are installed, the upper control arm has to be modified. (part of it has to be grinded away) we would like to manufacture a lightweight upper control arm with plenty of strength and clearance to mount a coilover shock without modification or compromise to the rigidity of the front suspension.

4. we need to come up with a stronger, purpose built, bushing for the shock end ....... we have had several customers indicate that the poly bushings fail after only about 6 months of driving.

5. we need to produce these parts, and design this suspension to use the same shocks and springs we have been selling in our basic kit, so that people can upgrade as they have the resources, without having to buy all new stuff. we hope to make available, to all the people who have previously bought our suspensions, all the fabricated parts in this kit separately.

enjoy the photos.

Part 1

buena girl started with a large piece of stock and has decided to make all 4 initial prototype pieces from it.

the second picture shows a finished stacker with a 400lb spring coupled to a 750lb spring.

heres a preliminary picture of the coilover shock with the dual rate springs and spacer to get the upper spring perch past the enclosed upper shock mount. the spacer was just finished up, its not compressed yet, just sitting in place. stay tuned for some test fit pictures!

pictures of the prototype kit under testing on js arms. notice the shock is mounted RIGHT SIDE UP AND NOT UPSIDE DOWN!!!!! look at all the clearance you have by the axel, and steering linkage :)

while we have been going thru the slow process of R&Ding components for the front suspension we have made a big improvement on the rear suspension and thoroughly tested it. all of our rear kits use a different length shock now, that allows full extension of the suspension. existing kits can be updated with an adapter to bring the old kits up to the new standard for very little money, and only about 2 hours of your time on a saturday afternoon. email jax@turbotime to find out more.

the front suspension kits have also been updated to use super strength bushings, an overall longer shock body, and be mounted right side up. all existing turbotime kits can be brought up to the new standards for very little money, and about 3 hours of your time on a saturday afternoon. email jax@turbotime to find out more.

still in the works are progressive rate dual spring setups, and custom fabricated upper control arms. stay tuned as we test the new components on daily drivers using JS arms and also stock arms...... yes i said JS arms. tired of wearing out your bushings on your JS kit? got a JS kit that you cant keep from rubbing on the axel or the steering linkage? we have the fix!
