If your worried about how dated the car looks maybe your in the wrong class? These are 30 year old cars, that's why they're cheap! Don't forget, Ronald Regan was President when these cars were built.
If your worried about structural integrity, just wait till your fire wall cracks!
If you want to take a removable liner and place it in your spare tire well, fill it with foam so you feel safe, I'd say go for it. Just remember that in a fire, that foam will go up faster than anything else. Not to mention the thick black smoke from the foam. Also, it doesn't
have to be in a direct flame to melt and smoke. I believe 944-Cup has a rule like that. If we're really serious about safety and fatigue, maybe we should look into getting a replacement fuel rail and allow the Lindsey Racing billet fuel rail.
As far as wheels, here's a set on ebay...

They are in good shape for only $550 which includes shipping. If you minus $100 for shipping that's only $112.50 per wheel. I'd buy them if I had the money.
Short throw shifters are a performance advantage allowing faster shifting. If we let this one in, it will increase the cost for everyone.
As far as increasing the class, someone said it earlier, when someone says Porsche they think $$$$. As a former Group 3-4 Leader, the Series Director needs to go talk with 3-4 and wrangle them in before they head off to TT or another group. Your not going to get everybody but 1 or 2 per year will help!! As 3-4 Leader I have pulled in 4 people in 3 years.
