Crappy Ride: Running 20" x 8.5" Rims on 285/50r20

Billy T If you think its bump steer check you caster angles and see if there in spec. I would say it should be about 3-5* for IFS. If it was too less than you will get a floaty feeling down the road ( you should know, you built 800hp VW's. I need pics to believe this )

I felt a huge difference between the stock squishy 265-70-16 and the 275-60-HR17's on LE wheels ....drove alot better and did feel stiffer ( which is what I was lookng for ! ) .... so ... YEA ...20's are going to stiffen it up a bunch ....

Also I bet those 20's are a ZR rating ... compared to the stocK SR rating in itself is going to stiffen the ride and make it wander !!

how about a video?

Then a pic...

We fabbed all of this stuff in-house.

Then a dyno graph...

only 718 at the front wheels, but it is over 800 crank easy...

My Pathfinder pulls this thing to the track

As for the PFs front end issues, I would hope that the caster is well within spec on a 6000 mile old rig. IMO, it is a toe adjustment that might get rid of some of the twitchyness. I might try to toe it in just a tick and see what happens... probably won't get any better, though.

Thanks for the pic. That VW is SWEEET....

Very nice. Makes me miss my N/A 2002 WS6 450hp Trans Am
