I'm with Jon on this one- a "roll cage extender" is not really a
valid way to improve safety.

You need to install a proper roll bar or a full cage. The other option
would be to install a hardtop, although TT Roadsters don't have that

Subject: More TT hoops

Another issue with open cars (we, the BoD feel), is that the open top of
the car doesn't do anything to keep arms from flying around. Even if
there is a 2"/broomstick rule in effect and the person passes, if they
roll there is a VERY good chance an arm/arms will be injured.

So, look for arm restraints to be the next addition to the safety list
for open-topped cars.

As for extender kits, I personally don't trust them. A bolted/welded in
roll cage is one thing. Something that is "designed" to be bolted to
existing hoops worries me. Has a vehicle with the extender on it been
rolled? Has it slid on pavement for 50 yards? What testing has been
