The vast majority of people Stateside have had issues with the track rods fouling the lower wishbone. There are several reported ways of tackling this... 1 - straighten the steering arm so that it's horizontal, then ream to take a TRE from the top. Don't like the idea of this as you'll probably have to heat the arm, so the upright could be fatigued as a result of this. 2 - a mark 2 MX5 upright has raised steering arms compared to the mark 1 (7mm difference). The TRE would fit as OEM. There should be enough adjustment in the steering design to remove any bump steer that this might dial in. The 7mm may be enough to provide sufficient clearance. This is how Keith Tanner did it after trying rose joints on mark 1 uprights. 3 - remodel the front edge of the lower wishbone to clear the steering rack completely. This is how it is on a MX5. Looking at the way Nathan has done it, I would be tempted to try a MX5 TRE instead of a Ford item in that situation. The cranked end of the TRE would bring the track rod down a bit, should still provide sufficient clearance for the lower wishbone and might reduce the amount of bump steer introduced by doing this. Here's an article I found on bump steer - http://www.longacreracing.com/articles/art.asp?ARTID=13 Any thoughts? |

So there is an option 3 available ; my problem is I've already got the front wishbones to SSC spec.

I really don't like the SSC front lower wishbone design it realise on people's ability to weld those adjusters a little too much for my liking, they make the wishbones overly complicated with no apparent need for them as there is an adjustable drag link at the top.

I've got the ssc ones and there is no fouling of the wishbones and steering arms. I have put a limit on the amount of lock available but there is still more than my passat has.

How much lock did you take off David (how thick were your stops?).
