What Ride Height Is This?

[Ricardo 0]

H there

Just finished beam refurb and reset the rear ride height

 

Wot do you reccon the drop in ride height is? It wasn't supposed to be this low The shock mounts were set with drilled bits of wood so they wouldn't move when inserting the TBs.

 

Just had it out for its first run in 6 weeks (I'm a slow spanner monkey!) once the battery was recharged it fired up immediately!! The little beauty Got the tracking set and it feels really good through the twisties but the rear is a lot lower than the front!

 

 

Tyres aren't catching but not really given it mcuh except on roundabouts. I'm gonna reset it tomorrow to sit about 10-15mm higher...

Advice anyone?

What distance did you drill the wood for the dummy shock?

 

Appears to be about a 55-60mm drop imo but hard to say as the camera angle looks to angling down slightly giving a false impression of the actual height.

Hi Graham, The tyre is level with the arch.

I set the centres at 307.5mm. There was no slack in the bolts/holes either. So should have been 35mm drop. (Bought the car with a stated 40mm drop but the beam was fubar'd then!

No wonder I kept loosing the back end )

OMG I hope I used the GTi TBs !! Just going to measure them now!!.........phew, GTi ones fitted!

307.5mm is about right iirc for a 55-60MM drop like I thought.

 

My front springs are 45mm drop afaik & even with 20mm tb's I've got it set bigger than that (310mm iirc) & the ride height is pretty level on mine.

I never was any good a sums! But going off the drivers site article std centres are 330.5mm

2.0mm of shock centre distance = 3.0mm of ride height. (so 20mm centre distance reduction = 30mm less ride height?)

Forgive me if I have this totally wrong but 2:3 is the same ratio as 1:1.5

then 330.5 - 307.5 = 23 x 1.5 = 34.5mm

but as can be seen this isn't right! So is it the figures or my workings? HELP!!!

The figures on the main site are taken from 205 Haynes manual afaik & they have never been found correct on any of the 205 beams I've done or anyone else afaik.

 

The Peugeot sport rally build manual states;

As a general rule, 1mm of dummy shock equals 3mm difference to the ride height.

Ta Graham, I shall never believe another Paynes manual! Mind you the one I have doesn't have any figures for anything to do with the rear beam assembly! It says leave to Peugeot garage with specialist equipment!

 

Anyway that explains why with the centres now set at 322mm it looks like this 4x4

 

 

Pitty there are so many differing opinions on the forum! But I suppose experience is the only way

I now know it must be 1.0mm centres = 3.0mm ride height!

 

Next weekend now before I re-adjust again! Glad I cleaned and greased everything up as the TBs now slide in and out without any knocking/drifting just by wiggling the arm and pulling by hand! I also learned the hard way which way the shock bolts go!

 

Thanks again for your words of wisdom

There is a topic by Jrod on here that questions the figures from haynes & I think it concludes that 322mm is about right for standard ride height.

 

Its nice when the bars etc fit in smoothly & are greased up, makes adjusting the ride height an hours work start to finish, wheels to wheels in my experience.

Took me 3 hours!!

Firstly the shock bolts.....lower beam sufficiently to enable removal

Then cos everything so slippy arms/ARBs etc were moving about cos I undid both sets of ARB plates and torx screws and shoulderscrew/locknuts!

Also the slotted caps kept turning when trying to lock the nut/shoulder screw.

I will do 1 side at a time infuture! Oh well.....you live and learn
