HOW TO DO AN ADVANCED SEARCH.
Mon Jul 08, 2013 3:56 pm by Admin
For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.
When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).
After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

rear bump stops
It appears like on my 85.5 that there is a pad where a bump stop should be on the trailing arm. Does anyone have bump stops on theirs, or know if there are supposed to be any? I'm hoping I can put some there to keep my tires out of the fenders on launch but maintain factory ride otherwise.

I thought I posted dimensions of the ones I made that adapted the VW poly bump-stops to the trailing arms...

I believe the old vw camper vans used p/n 211501191. Mount & fit same as 944...just taller.

Mine mounted the shorter bullet style mounts that come in rubber or poly.

Hugh, don’t remember that one, and I thought I had stolen all of your good ideas.xschop wrote:I thought I posted dimensions of the ones I made that adapted the VW poly bump-stops to the trailing arms...

Re: rear bump stops
944convert, do they still work despite being taller? They look like they would sit in that bowl well, but how exactly do they mount? Looks like a nice, inexpensive option.
xschop, I tried searching for anything bump stop related in this forum and came up empty, but I know the search function can be finicky.

Re: rear bump stops

On one car we wound up trimming about 3/8" or so off the top of the bullet to give the car more squat and a better launch.

Re: rear bump stops
How did this mod work out for you? It seems like you were having launch issues. Prevents cut tires with soft springs? I assume you drill and tap the trailing arm casting where the stop should have been. The area where it would hit the frame looks kinda rough/sharp, did you put anything there?

Re: rear bump stops
simply pull off the existing rubber bump stop and push the replacement onto the mount's metal nipple.lsporsche wrote: but how exactly do they mount? .

Re: rear bump stops
Correct. The arms were just drilled/tapped and a simple slight hammer job to the wheel well area. This was a simple and effective solution on a couple 951s that did some drag strip time but also were Dailys. No rear coiloers and torsion bars to mess with.

Re: rear bump stops
I spun you a set out. Will get in mail mon.
Heres the dims for anyone else. You can drill 5/16" or 8mm thru-hole and just tap your control arms accordingly.
