More expensive or less expensive than the other options?

markp27

If I buy from my local dealer, he'd be cheaper, but in terms of other well known "mailers" about the same. But I couldn't find these parts (except the diff adj and the shock inserts) anywhere else.

Thought I'd give them ago. Good result.

Your PM is full again

Where you at, Herbie?

I'll definately be ordering more from those guys - they've earned a place in the FAQ

how much upstop do you use with new tires

markp27

Hi Rodrigo,

Check out the FAQ section "Droop for larger tyres:" I've just posted the FAQ a couple of postings before yours.

All is explained there - if there is anything unclear - fire away.

Cheers, Mark.

Just to make things clear, upstop and downstop are two different things.

Upstop is almost never used.

For downstop / droop settings with 66 mm new tires, +2 and +9 for the front and rear respectively interpolating from the stock setup of 0 and +7 in the front and rear with 62 mm tires. Both situations will be 6 mm ride height.

I think you mean "don't drink and FLY"

I think Julius has been away from his lady too long.

woohoo Mark, no more wobbly shocks on your car for sure!

Maybe I need one too

markp27

Oops, I should read better

Did you mean upstops, Rodrigo? Upstops aren't usually used - I've never had to use them, at least.

Upstops are the screws which limit how far the suspension arms move in an upwards direction.
Downstops limit the suspension arm's downwards travel.

Cheers, Mark.

Such toys - you NEED these things

It's a nice piece of kit - made from Alu and the pivot gauge has a ball bearing for smoother operation - NICE!

HI, I do know what upstop means and I did ment upstop I was just wondering if anyone used it

rodrigo1508

what I dont know is when I should use upstop and how much

markp27

I wouldn't use them. The idea is to stop the chassis bottoming out, so you could set them without your shocks on, so that they stop just before the chassis hits the ground.
I do believe, though, that they have a un-desirable affect on the handling if the suspension arms travel far enough upwards to the point where the upstops stop further travel.

Maybe a question for Julius - under what circumstances would one wish to use upstops?

Cheers, Mark.

I did remember Julius or some team driver (Art Carbonnel) mentioning about it at mytsn. If I'm not wrong, you only use it when the conditions are very bumpy. Else do not use it. The upstop is set just enough to prevent the chassis from bottoming out.

Like what you say, it makes the suspension do weird things. The shocks hit infinity when the upstop screws are met.

BTW, there are no upstop screws on the 710 if anyone is interested. Just the front.
