I used the power of google to look, and there are various thread I have found talking about converting 93-97 cars to the 98-02 style front bumper but not much out there on converting 93-97 cars from the TA to Formula style or vice versa. I have a 97 TA WS6 that now has some damage to the front bumper/cone, and I am considering swapping it out for a Formula front cone with an added front lip/splitter like I found on this listing of a modded 1995 car:
I am wanting to know how involved a conversion like this might be and what parts might be required, other than the bumper itself. A different foam crash bar? Other stuff? Of course, if someone knows where a guide for this already exists, a link to it would be really helpful.
