Looks like that company is doing some neat stuff. I would like to see their mounting methods of the 20B and 23A into the FD chassis without modifying the firewall.

So what would be the ratio then?Is the 20B a 50/50 ratio?

Mazderati 01-31-2004 03:08 PM

A lot of it would depend on how the 20B was mounted in the FD.



If one were to modify the subframe a la Pettit and the like, one can expect the ratio of front:rear weight to be altered. An end result of something close to 52:48 or 51:49 is probably to be expected. This could be combated in part by removing air conditioning, air pump and power steering systems.



However, if one were to modify the firewall and related components the weight ratio front:back would probably be very close to stock even with leaving all stock components in place.

they redo the subframes to put it way low in the car. at sevenstock the 4 rotor car was a doorstop but the 3 rotor car runs

4RotorRocket 02-08-2004 07:53 PM

I wonder if they did modify the firewall or not im gonna ask i'll post up their reply.
