997.2 GT3RS approach angle

Recommended Posts

Hey guys, Quick help appreciated....

I'm pouring a new driveway tomorrow and need to know the approach angles for the 997.2 GT3RS. I have the front axle lift so I'd really like to know both angles: with lift up and down.

I've done a few crude measurements but wanted something more official so I can rest easy after the mud goes down.

Thx.

I can't give you any exact angles but I know it has to be very shallow with the lift is down. Mine barely clears with the lift up and my drive isn't very steep. What I would do if you want to know the exact clearence angle is put the lift up. Then put a string under the front tire and pull it tight to the bottom of the front lip spoiler. You will be able to use a angle finder or a speed square to get the exact angle. I hope this help and good luck. :)

Jermmy,

Thanks man. I've already done that exact thing and using a little geometry (inverse Tan) calculated a couple of angles. For peace of mind I was hopeful someone might have the actual angle published from Porsche. I found the data for 997.1 RS but still no official numbers for 997.2 RS. I'm getting 5.6 degrees and 9.14 degrees with my crude measurements. These were calculated with 18in rims with hoosiers but they do have similar OD as OEM.

Your numbers sound about right, maybe a little steep if you are wanting to drive straight in without coming at it with an angle. I was guessing about 8 degrees with the lift up. My drive is about 14 degrees on turn in and I have to come in on a 45 degree angle with the lift up. I barely make it with about an 1/8" clearence. When I first brought it home I had to have my wife get out and watch to see if it was going to clear, lol. With that said I don't scrub the lip too much but I do scrub the deflector in front of the wheel all the time. For some reason it seems to hit things that the lip will clear.

Have a good one.

Jermmy
