Yep your absolutely right dandywarhol, this link you provided is the cheapest. They take 3 days to deliver though and i wanted to get sorted for the South West Fest so was happy to pay the extra couple of quid to have them there and then.

Spot on advice though, thanks again.

Does adding spring assisters really affect the ride that much? I rarely bottom mine but am conscious of the "rolling" effect from the Bongo. If it smooths the ride under normal conditions as you say then I'm all for getting a pair myself.

Its definitely worth it. I noticed it on the M5, you know where bridges surface joins its always a bit uneven - settled immediately after. For less than a tenner (see dandywarhol's link) and half hour of work its brilliant.

I've changed the springs on mine to lower it, so to make sure you get the right ones, jack up your vehicle and measure the distance between the coils in centre of spring. from the bottom of one coil to the top of the next one. When you order tell them this measurement in millimetres so they send you correct size.

Simple to do; Put the kettle on, get a pan large enough to fit spring assister into, cover in boiling water and simmer whilst you go and crack the wheel nuts on both rear wheels. Jack it up. Take one wheel off, wipe the spring over, put some washing up liquid on it. Go and get one spring assister out of boiling water (wear gloves) put some washing up liquid in the grove on the spring assister and feed onto the spring. Wheel on, lower and repeat other side.

and where do you position the assister between the middle coils?

...which makes me think. Were you using your technique to get the spring assister on to a nice new shiny spring, and would the same approach work on a 12yr old somewhat corroded and pitted original spring. I'm writing with my eyes shut of course as I haven't got any idea what all the various parts look like etc.

Jeebus Mike - try to keep up.....................

It's the black bit in the middle of the 12 YO rusty ol' spring. I also felt it helped to cut out some of the "yaw" on undulatory surfaces but the bump stops still hit with people in the back or a motorbike on the towbar. I'm looking into getting air assistors next.

Ah! I'm unblindfolded now and can see my fears are groundless.

Thank you for those kind words dandy

Mike, your right i did have the advantage of still paint covered new springs. However I found Tesco own brand of washing up liquid an excellent source of lubrication and this will assist you in feeding the spring on!
