Angle of entry

Post by maddog2020 »

Does anyone know what the angle of entry is for the 928 on driveways? We are looking at a home that has a steep driveway downward into the garage.

This isn't the answer your looking for...

... but since it's ride height dependent doesn't it make sense to measure your 928 as it sits?

If yours isn't 'sitting' then give me a ballparky ride height and I might be able to measure one of the three I have that are sitting right now.

mines hanging right now... lol as usual. I'm running 265/35/18 with a diameter of 25.4" I don't have the ride height set yet but my plan was to take the standard height and add half the diameter increase to keep all of the suspension geometry optimum.

Measured mine and am getting 11.5 deg. max. Stock wheels/tires/ride height. Center of the black part of the front fascia makes contact. Pic showing area I'm talking about.

A lot better than the GT350 (7 deg.) which scrapes everywhere.

The picture with the wheels dangling begs for questions to be asked.

Was the suspension settled when you did the approach angle measurement?

Yes, car has been sitting. That was just a older picture I pulled so I can point to the location that would hit first.
