I have a widebody (turbo-look) car and have converted the rear trailing arms to narrow body. I have been told that I can move the front suspension to the non-turbo (inner) settings. Just curious what this entails. Is this a straight forward change and are there any downsides?

Just move the bolts to theses positions. Crossmemebers are the same, A arms are the same. You may need different outer tie rods for the appropriate adjustability range. Check the PET to see if they're different.

Greg Wolfe

Thanks. After doing some research, it seems there may be some downsides to doing this. Has anyone made the move without issue while pushing the car?

I've been using it 9 years already. What issue should I except?

30% of my annual drive came from race track.

I've read it was a common move for wide 993 guys to allow more tire to fit under the fender, but only anecdotal information.

Are you talking about adjusting the settlings on the front longitudes?

Like Mikke, I am running the narrow body settings on a wide body. If you want to do the switch, you simply rotate the top mounts 180 degrees, move the longitudinals to the narrow setting, change the tie rods and sway bar.

Greg Wolfe

Yes

Thanks Laurent. Do you happen to know the exact measurement difference if I was to figure out a new wheel offset?

Per Bill V when I checked with him, 30mm difference per side.

It is 30mm per side difference. AFAIK all 993's use the inboard setting but the longitudinals are different pushing the track width out by 12.5mm per side over 964 NB inboard settings. I have driven on track with the 993 longitudinals in both NB and WB settings. IMO the car handles much better in the WB settings. I can only assume with the 964 longitudinals it would be even worse. Much more controllable and takes less effort in the turns with a manual rack with the WB settings.
