I was gonna buy a cheap mugen style top:

>> Hardtop must be OEM/OEM option or OEM/OEM option shape and size only, an a rear window. (ie., lightweight ok, but no tops with non-OEM aero features).

only other thing I see is street tires +2

 

very good to know. thanks.

 

Does a Mugen style top really provide more of an aerodynamic advantage over an oem top? I can see the Spoon top being an advantage if you have a gt wing due to the gradual rake, but the Mugen top seems pretty close to oem, aerodynamically.

 

yea I was hoping someone with a mugen style top would protest it

Its gonna be a lot more expensive to buy an OEM

 

I would think the Mugen top / replica is considered an oem option shape and size. You should email the TT director.

 

Yea, get it in writing cause I'll protest your Mugen

 

What page in the rule book are you seeing the hard top stuff?

 

Hmm... that's a PIA of a new rule! I guess we'll see what the TT director has to say about it. As the rule is written, I would say a Mugen top would not comply and need to take the +2. However, it might be possible to lobby to make the Mugen top an exception. I suppose it depends on what the intent was when writing that rule... and only one person knows the answer to that question.
