axle hop
Anytime I revved my Boxster and launched from a standstill I'd get wheel-hop. I just took a 996 TT for a test drive and no matter what I tried it just hooked and went. Does your Boxster launch cleanly at say 3-4000 RPM's?

My 01 Boxster S does not wheel hop under those conditions. How are the struts and bushings?

He just put in the new style motor mount. I asked him if he got the side stops with it and he never answered back on it.

When I had wheel hop on my 2001S it turned out to be a bad shock/strut. Swapped it out and problem solved.

Boxsters all wheelhop if you really get on it. Not good for your pinyon bearing and may lead to failure. Learning to do a smooth launch without damaging the clutch or transaxle is a tricky business. If you like to do a lot of stoplight launches, add an LSD or start shopping for a spare trans.
FYI: A 996 TT is all wheel drive with LSD. They always launch great.

I need to get the 76 914 running this summer so he can learn on that one.

I don't get any wheel hop with my '99 which has 19' on it with 275's on the back.
I know just where the clutch will "bite" and can launch fast and hard smoothly with no slip...
also, if you're going to teach someone to drive a sports car, learning how to correctly blip the throttle down shifting takes a huge load off the drive train...

Installing new ROW 030 struts helped a little just as a new front motor mount (had to re-use the side pieces) did. I always wondered how the newer cars equipped with the sports crono pac could spin to something like 6000RPM and than launch netting 0-60 times in the magical 3's and4's. For a short time I ran some old fronts (225's) on the rear and could hardly notice a difference (including launching)except as cornering speeds increased (and especially during transient maneuvers).

He hit 1st on a 2nd gear upshift?!
Seriously, buy an old Corolla, Civic or Cavalier for him to beat up on and wreck until he figures it out.
Probably less $$ that way than a clutch & tranny for the Boxster...

I have a UK made version of this. I can't say it stops axle tramp and I can't say I notice much difference in day to day driving. Hard to tell the difference when driving in extremis as I'm not measuring lap times and only going by feel.

I have a Tip so it's hard to get wheel hop and I've never experienced it but it does strengthen the suspension much like a strut tower bar. My trusted mechanic stated "it can't hurt." I only posted it for you as a lead so you could contact Pedro and ask him questions.

A bit more expensive, but if you really want to beef up that area, here you go.

So are the braces stopping wheel hop or is a limited slip dif the only real cure?

I know. all of our other cars are automatics. I put him in one of the old ranch trucks a couple of weeks ago but its nearly impossible to stall. low gearing and big diesel engine.
