I'm currently rebuilding the rear suspension of my 1988 944 Turbo S to coilover.

When removing the rear dampers I figured it would be difficult to fit a rebuilt damper with coilover on the right side since it's pretty tight with the transmission oil cooler.

What do you guys that run rear coils say? Can I fit 2.5" springs?

I don't think so, man - I have 2.25 and it is VERY tight.

Dan Hovang

Guess I should prepare myself to possibly replacing the oil cooler with a different kind and also relocate it ..

We've got 2.25 on the track car, 89 transaxle with cooler, and Jim is right, it is tight. If the springs are new, you should be able to return them for 2.25.

I have 2.5" rear springs and the cooler loop. It can be done

What kind of dampers are you trying to run Dan? What style of lower mounting point?

I've got 2.5" rear coilovers on my TS (with the loop). It can be done. I moved/bent the loop a little away, and flattened some of the fins, and wrapped them to protect it (just in case).
I haven't noticed any sign of rubbing....

Dan Hovang

I'm going to run rebuilt Konis with standard bottom/top mounts. So it's not a bolt-on kit.

2.5" springs ate mine.
I gently bent the loops for clearance, but apparently it wasn't enough once on the track.

If you think you have JUST enough clearance between the cooler loop and springs, remember that your tranny will move under hard cornering loads because of the rubber mount holding it to the chassis. Your small amount of clearance may not be enough.

Not the best photo, but here is the right side of my car. As you can see, the cooler has rubbed against the spring a bit, but it isn't bad.

Here is the left side just for kicks. Man, what a clean car!!

Dan Hovang

You seem to use a custom bolt for the lower mount Mike. As I recall, the original mount does not build as much as yours, so your spring is closer to the cooler than mine would be.

Great pictures!

Dan - he is using the racer's edge shock mount - and YOU need to use it too if you are using real shocks with 1/2" spherical bearings. If you use such a shock that is designed to be in double shear with the factory single shear bolt - you'll bend it over.
The factory designed escort cup shocks are designed to use the factory mount so they retain a thin rubber mounting eye - and it is reccomended that you keep the t-bars with them.

So if you have the tranny cooler there is no fix for this? I ask because I had plan to take this path some day.

Sure there is - 2.25
