I have an MK Indy R with a set of 15'' Alloys on all round. I just fitted them today and found after 1.5 turns of the steering wheel, the
inner portion of the wheel fouls on the wishbone.
I assume this is a common fault and I need to restrict the movement on the steering rack itself?
Cheers
Does it do it both sides the same?
What width/profile tyres are fitted?
^^ and what offset are the wheels
Tyres are 195/45/15 Toyo T1-Rs with Rally Design Alloy wheels (ET38mm) and yes the same on both sides unfortunately

Yep, mine did that. I made up a pair of sleeves that go around the ends of the fixed section of the steering rack to limit it's travel. You have to be very careful if you go this way to ensure that it couldn't accidentally jam the steering if it failed, and that Mr IVA tester doesn't see it.
Drop a collar around the rack pinion (under the gaters) to restrict movement, some people use jubilee clips I prefered something more solid.
So a common fault even though the wheel offest is correct according to MK?
How very interesting! Thanks for all the input so far guys !
have you got a bigger photo?
from that tiny photo, it looks like you only have a lower wishbone on? is the whole system fuly built up?
you can but collars from radio spares (RS) which is a plastic ring clamp thing, think people use those to limit the turn
something from here

Offset isnt the only contributing factor, the width of the rim counts for a lot, if you have et38 rims that are 5.5 inch wide and go up to 7 inch wide
but keep the et38 you add half the extra 1.5inch to the inside edge.
Im not sure what MK recommend as standard, but if its based on standard Sierra alloys this may be the difference?
Sorry blakep82, this is all I could manage in a rush. However in answer to your question yes my suspension is fully set up. From everyone's
response (which is why I love this forum) a restrictor clamp on the rack seems to be a solution to my problem.
One step forward, two steps back hey ! lol
loggyboy, you are right. The fact they are 7'' wide contributes to the problem. However Ive noticed alot of MKs with Team Dynamics 1.2s and im sure they only come in this width aswell. Not to worry, Ive found some closure lol !
not a design fault just the result on all of this type car of not having a dedicated steering rack

The 7" wheels are the problem min has 5.5" up front an no problems you could aways fit a wheel spacer

Surely a design fault then. That is, designing a car to be used with a steering rack that doesn't suit.
not something I would want to go wrong.. quote:

No not a design fault if you used the sierra wheels it's fine. As others mentioned as you change the wheel width you also need to change the offset to avoid this. The only problem I had was the wing stays fowled on full lock, fixed with hammering a ding into the wing stays, now I have a turning circle that would put a london taxi to shame; personally I didn't like the idea of modifying the rack (the same goes for the spring fix for self centring "fix"

Ah. I understand now. I stand corrected

If you change Offset, then you change Scrub Radius which may be detrimental to self centering.
