Nitron package adjustment ,help!

[howardm]

Fitted by tvr dealer about 18mths ago. very pleased but the ride height which was already lowered compared to standard has settled to the point it grounds occasionaly and therefore needs to be raised.how do I go about this and do I need special tools?

Depends whether the threads for the spring seats have corroded, or rather how badly they have corroded. If they're still reasonably free then you just need to jack each corner up and take the wheel off, grab the outside of the spring firmly with both hands and turn it to wind the spring seat up the body. You need to check the position of the spring seat to ensure you set both sides the same, the easiest way to do this is to count the number of threads under the spring seat. If the spring seats are too stiff, try oiling the thread and winding them down a little to work the oil into the thread before you try to wind them up.

If you change the ride height then you will need to check and reset the geometry, but if the ride height has dropped this will probably be out anyway.

Howard,at 18 months old you hopefully wont have corrosion problems on your Nitrons,as theyre anodised alloy.If you call Nitron they can supply you with a 'c' spanner that has the dowel locator to fit the spring platform,if you buy just any old 'c' spanner youll probably have to file the locator at the end,into a round shape in order for it to fit.Clean and lube the threads before you start,then all you do as Peter says,is just rotate the platform until you get the required height.Do this with the wheel lifted from the ground though.

You can get/make a suitable C spanner (a standard C spanner won't fit properly) but I found after going to great lengths to make one that was perfect for the job, that I didn't need it. I can adjust mine just by getting a good grip on the outside of the spring with both hands and turning it - with the weight off the suspension, and the wheel removed for access.

Thanks for the tip Peter,i must admit i find the Nitrons a lot more fiddly to adjust with the dowel type adjuster for some reasonThe 1/4 'c' spanner they supply keeps wanting to slip off the platformNever occured to try it by hand!!

I use a 6mm drill bit, fits in the holes perfectly.

Thank you all for your comments/tips which are very helpfull
I did`nt appreciate the geometry will have to be checked and probably reset and that is beyond me.My local garage who specalise in EVO `s have done a few things on the griff and said they will do this if I want.Do any of you have the details of the settings for the geometry?
Sorry to pester .
