Hi Edd
are you going to be racing the D4 at all or why are you trying to strengthen it so much. I dread to think what you're up to after the roll cage question a couple of days ago
Maybe a D4 is not quite the thing to jump off roofs and things... You can get really good basher models that will take alot more abuse than the kits designed for racing.
As for your speedo, it won't happily take anything more than the motor you're running at the moment. If you want something quicker you will need a new speedo as well.
What do you mean with "worth the same" with the 6.5 and the 5.5???
Also stay away from fiberglass and aluminium on your D4. Fiberglass won't do a thing for strength, make the whole thing heavy and look like someones been sick on your car. Aluminium wishbones or "wings" as you call them are bad! Weigh a ton and really do nothing for strength.
How old are you actually? It might be an idea to read the forum some more lest you turn yourself into Bmag-reloaded
