antonio Posted November 17, 2015 Share Posted November 17, 2015 good morningfollowing my engine transplant, i have to find a way to make sure the diff mounts will be able to deal with the huge amount of torque the engine will produce.i already have the CC diff braces fitted, but i wonder if something else can be done, never mind if it needs welding new tubes etc...best regardsantonio Link to comment Share on other sites More sharing options...
Mankee Posted November 17, 2015 Share Posted November 17, 2015 Hi Antonio. It might be worth speaking to a local to me club member Gerry (2GBR, http://www.lotus7.club/users/2gbr) about this. I think Arch modified his race chassis so that the third (?) fixing bolt on the Sierra diff can be used to hang it on the car, instead of the usual two fixings. Something like that anyway!

2GBR Posted November 18, 2015 Share Posted November 18, 2015 Hi Antonio having seen your posting i thought i would reply, Yes Bruce at Arch Motors has done several S3 chassis with an extra diff mount which is box section brazed to the same size box section at the rear of floor pan and are approximatly half way between centre line of chassis and side of the car and come up at a slight angle to a standard metalastic bush which goes through the rear lowest sierra diff mounting. A very well triangulated extra mount. Unfortunatly you can not use an over chassis anti roll bar only an underslung roll bar will fit Regards Gerry Link to comment Share on other sites More sharing options...
