    Iirc Dewis on Vauxsport and Mig made the tie bar shorter by increasing the threaded part by 15mm to pull the wheel forward

    On a Nova? Dewismotorsport?

    Edit, found it. On a Corsa coupled with adjusted top mounts:

    James (Jonlem) on here does rose jointed adjustable track rods & tie bars.

    The adjustable top mounts as they sit inside the front turret your restricted in the amount of adjustment you can actually get.
    I did see recently a rally nova Colin had for sale / breaking with the top mount located on top of the turret.
    This is something I have thought about & presume there is a reason why more don't do this.
    I would have thought if you strengthen the turret then there is no main reason why you can't do this.

    Any thoughts on this appreciated??

    My honest opinion on eccentric top mounts is that they're waste of time.

    I would go for adjustable tie bar and bottom arm setup

    Just found the picture from Colins for sale thread.

    Top mounts like this i was on about.

    May get more adjustability going down this route.

    What is to stop you running them upside down? Serious question.

    Martin I guess running them like that is putting the weight on two M8 bolts rather than the whole strut top area.

    Mark nothing is technically stopping you from doing that, that's what Trackdaynova did, I personally don't fancy the weight of the car being sat on a circlip in a machined bit of alloy though?

    I thought if I chopped the turret "lip" out it'd give me more backwards adjustment, however this thread has made me look into tiebar mods before doing that so my turrets may survive for now

    Weight of car wont sit on circlip as that is under the bearing.

    Agree on weight of car on the threads in the top mounts, but that can easily be sorted by either drilling & tapping larger bolts or drilling right though & having a nut welded inside the turret to screw into.

    Ford boys run them on top so must be possible.
