Pan Skirts

Tire growth is very relevant when it comes to designing the bottom of a liner. A 30" Mickey will be more than 2" bigger at about 400 & that will vary with the rim width.
For that very reason, the bottom of my liner is not flat, it's tunneled with a large radius on the outside edge to match the tire profile.

Hi Sid,
As you may know the Simspeed design uses all aluminum wheels so I don't think tire growth would become a factor in this regard.  Thanks... Terry

I'm not following your threads very closely here Terry but you would get more of my attention if you started building. There have been a number of liners over the years where solid driven wheels have been tried but I don't know of any that worked well enough to keep them, do you?
I was hired on to the Herbert-Steen four engine liner back in the day, then we changed from solids to 30" Mickeys & that took a lot of work.
