pinto
ive just purchased a 2.0 pinto, sierra complete, what are the chances of me, using all the running gear ?
i know most people use a 4inch wider chassis! ie robinhood.
ive based my chassis on the book, but all the dimensions are for the xflow, any 1 used pinto and running gear but with the book based chassis, cheers

I'm building using a 1.8 pinto & sierra running gear and the McSorley +4 plans. It's going ok so far (am still on with my chassis). Rear end looks
like it will go ok, as does the engine (though i'm considering changing to a rover V8).
Front end might be a little trickier... going to need adaptors for the mcpherson strut mounts, and will have to look at getting the steering rack
shortened i think.
I'm going to get a copy of the Avon book (c/o Amazon to do my bit for the website!  ) to see how they address some of the problems.

Jay,
You will have issues with the running gear. If you shorten the rack (make sure you do it at the 'body' of the rack not the arms (for bumpsteer))
then you're front track is going to be narrower than the rear. This may not be a problem- there are advantages and disadvantages to each.
John,
If your chassis is 4" wider then do you need to change the rack? Remember, the difference between the Sierra and Escort track is between 3.5" and
4" anyway. If your chassis is this much wider, as long as you have standard wishbones the front should be fine.
Unless I'm missing something of course.... in which case please tell me as I'm trying to overcome this problem myself at the moment!
My chassis is about 2.5" wider at the front (and I'm using IRS) so I'm considering increasing the wishbone length slightly to make it up to the
full 4" to match the back. That way the rack can be standard,
HTH,
James

I did a quick "test fit" at weekend (i sat the rack on the bottom chassis rails)... the steering column looks like its going to be right in line
with the offside FU rail (which i've not welded in so far). I haven't yet looked in enough detail to see if i could come up with any kind of work
around for it.
Also, from memory, i think the steering joints were outside of the line between the wishbone mounting points on the chassis
What do MK do with relation to the Indy's steering?... their website says a modded exchange rack is supplied. How does the width of an Indy compare
to a book chassis? Or do they run different front / rear tracks?

Been wondering that myself. I know they chop the rack for their Indy- they cut out part of the middle. But I thought the chassis width was standard. I
guess therefore the track is much narrower at the front.
Could an Indy builder confirm please?
Thanks,
James

Longer wishbones. The rack is shortened in the body and extended at the rod ends. This is done to eliminate bump steer. The track is as per sierra.

the for the help guys, i should have worded it different, i was going to use a kent, and my chassis is based on the kent, its same as the book, its
NOT 4inches wider or longer, so is it still poss 2 use a pinto??

Having used the pas rack from my granada donor (similar to sierra) i can confirm it will get in the way of the front susp supports. I used the rack
unmodded, but to fir it had to mount right at the front, behind the rad, (to get min bump steer) and i had to modify the chassis quite a lot to clear
the shaft. Having been through it all, i would suggest you get the rack shortened so it clears the chassis and sorts the bump steer at the same
time

Simply, it is toe change (i.e. steering movement, usually unwanted) caused by the vertical movement of the front wheels (usually fronts, although It
can apply to the rear)
Ideally you want the wheels to go up and down (both cornering and over bumps) without changing where they are pointing.
