Question to sliding pillar owners - How much clearance have you got between the the stud/nut on the bottom of the fixed strut and the inside of your wheel rim please (and what size rim is it)?

 

I have the ride height set fairly low on mine at the moment. The standard springs have been replaced with shorter/stiffer ones and am using a thick bump stop underneath the hub to move the hub up the pillar and effectively 'drop' the front of the car. With 15" rims I currently only have about 40mm clearance to inside of wheel rim!

 

There is more than 40mm travel available in the spring above the hub - so theoretically the nut could dig in to the inside of the rim and cause a nasty accident once its roadworthy. I can obviously fit a bump stop on top to try and restrict it to 40mm to prevent it contacting.

 

What I'm wondering is though, how much travel do we normally get in 7 type cars front suspension on the road? I've watched youtube onboard videos of 7 type cars where you can see the suspension moving a lot on the country roads - but these have all been wishbone car videos. Obviously the sliding pillar design is just terrible and can't be compared to wishbones of course so its difficult to judge - but am I worrying unnecessarily? Is 40mm plenty assuming the spring is pretty stiff? I'm guessing not and thinking maybe 50-60mm absolute minimum travel required?

 

If there are people running around in sliding pillars with similar clearance possibly using the softer standard springs then hopefully I won't have to worry about it. Would appreciate peoples input though please.

 

Cheers

Tony :)

Hi Tony

Just measured mine and I have 72mm clearance with 14 inch wheels. Maybe worth putting a photo up of where you want measuring just to confirm I have measured the correct gap but I think I've got it right.

Hi Tony

If you remember I sent you some pictures of my setup in 2013.

I have measured mine and it is approx 60 mm from the under side of the cap screw to the wheel rim using 15" wheels.

Can send some more pictures to you but tried to attach here but The server returned an error during upload  

 

Regards

 

Martin

Thanks for that chaps - that's really helpful  :)

 

Rich - Your description says you have a Sub-K though, they have a different front suspension setup don't they? As I understand, it's kind of a wishbone type link arm setup on the bottom and then a spring/shock above acting against a fixed arm on top isn't it?

 

Martin - Yes I do actually remember your emails, I never could get the images to enlarge enough to see exactly what you did with those nice machined adjusters though unfortunately. I've just replied to it again from my hotmail account, hopefully you got it ok? I would love to see some pics of how it all currently looks.

 

I will grab some pics of mine this weekend and try to upload them (anyone know of a decent free hosting site now that photobucket are trying to hold us to ransom)?

 

Cheers again for the replies

Tony

Thanks Martin! Great pictures - cheers again for getting them for me. As said in the email, I really like what you've done with the machined parts and adjusters etc!

 

Cheers

Hi Tony and any others with sliding pillar front suspension here are a few pictures that I am able to post at last, as to how I have modified mine.
