Hmmm...I'm not a car guy, but isn't the point of the large diameter wheels for low profile tires for high speed cornering?  In a racing car, as you go around the corner, the sidewalls flex because of the centrifugal force that they must transport to the car By using low profile tires and

It's all relative. Relative to the road the bottom of the wheel is in fact /almost/ stationary. There is a tiny bit of slip, depending on whether it's a driven wheel or not. Obviously if there is a lot of relative motion between the road surface and the bottom of the tire, then you've lost

Bill; No worries on the Audi spring swap. I went into it with eyes open, just the tip that the springs were compatible helped me move forward. I think that a complete spring/shock assembly *is* a drop-in replacement. Whether the ride height is completely stock afterwards is open to question,

I was certain that the Audi 4000 springs were a drop in replacement on the Rabbit. I perhaps the springs varied in diameter from year to year, or perhaps according to the country. Sorry that the spring mounts on the Rabbit needed to be changed. :-(  Not such "good" advice, considering the

Great tech advice as usual, Bill. Contacting a wheel repair place here in Oregon (Eugene area is the closest), I find that straightening the three slightly deformed 14x6" factory alloy wheels that I intended to use is $150 each. I about choked on that price, then I found out what a set of

I would steer away (so to speak) from wheel adapters. They are a kluge at best and dangerous at worst. 4x100mm is a _very_ common size. Supposedly, there are 850 different car models with 4x100mm wheels: https://sizemywheels.com/lz-pcd/4-100   and about half of those have a 38mm offset (ET):

I've used Nokian WR and WR G2 tires with very good results. They'd coast a long way. Mine weren't horribly noisy. Wear rate was so-so; anything over 40k was pushing it. Nokian make an LRR WR G4 (later generation) tire in 185-65-14. Would that work? They will probably be hard to find, and
