MC Sorley 7+442 with Sierra gear
I just (pickingup tomorrow) got a McSorley 7442 chassis and have a Sierra lined up for spares. 1.8 Pinto - no problem but......
I want to use ONLY parts off this donor. So, if I do the GTS DeDion rear end, do I need to do anything special at the front? I want to use the Sierra
rack if possible without modification and I saw that GTS do bigger wishbones - is it just a case of putting these on? This would give me the same
width on both sets of wheels (like the original car) is that necessary? Should the front wheels be closer together?

sierra
its best to have the same track width at the front and rear
you will need the steering rack shortening
if you dont you will have massive bump steer
you then make up the missing rack width with extentions gts sell them
ring darren and he will help you

What is bump steer mate? Or am I being stupid and its as simple as the steering bumps at full lock?

Nope, it's when the wheels go in or out when the suspension go up and down.

best (easiest) way to avoid it is to try to ensure that the joint in the steering arm is between the upper and lower inboard wishbone pivot points,
and that it is parallel to the lower arm.

Not just the massive bump steer, the Sierra rack is WAY too long to fit into a Locost chassis. The input shaft lies outside the chassis with a
standard width car, and is almost exactly inline with the FU tubes in a +4" chassis.

Thanks for that fellas - I hope I get all this in my head before I start the build - I think I've got most things sorted but there's just
the odd thing I've never encountered before.
I reckon I'll just go with a new rack for what it's going to cost. Will a MKI Escort one fit or does it have to be MK II as I've
seen a MK I for £25!!
