MOT Fail on suspension too firm!

[jamesis2]

About a month ago I fitted the KTR Coilover suspension kit from k-tech. Adjusted it so there were 49 threads visible between the bottom locking ring and the start of the tread. Was running fine, not too low for speed bumps etc but today I gave it to merchanic to get it MOT'd and it failed!
It failed because the 'bounce' test i.e. push down the front of the car to test the shocks, was too firm! They said it needs to be raised.

Does this sound right? Anyone know the min height?
Car is a ph1 172, x reg.

Hope that makes sense!

Cheers,

James

Never heard of that before.

KTR kit too firm... Lol hardly... On a serious note I would look into that as mine was MOT'd today with Vmaxx coilovers which are probably the same stiffness/more stiff and it passed fine with no problems.

 

[Daniel]

Never heard of that in my life.

 

[Naith]

youve been had!

 

[r_dizzel*]

what
the
fu*k!??

 

[jamesis2]

I think that it's because the MOT tester is an old chap stuck in the 1950s or something... I just want to check first make sure it's not me being dumb or something!

I just don't understand how it can be too low :dapprove: If they do change the height it's gonna cost me another £££ to get the alignment & camber fixed again.

 

[Dave..]

Take it to an MOT tester who will pass it, not one who's trying to get money out of you.

Edit: Ride height has very little to do with how firm the ride is.

 

[jamesis2]

It's really annoying me that a merchanic and MOT testers don't know anything about this sort of thing and come up with it's too hard because it's low. Perhaps they think it's running on bumper stops or something... I'm gonna be unleashing the fury in the morning

 

[ForceIndia]

How long till the MOT's up? Isn't there an appeals process?

 

[legohead01]

can't fail for that im a tester.

 

[Hutchie]

if when jacked up the spring is loose then it is indeed a fail.

 

[Henry]

what does it actually say on the failure sheet?

they can fail for things like fouling on lock due to lowered suspension, but not stiffness of the dampers/springs i didn't think S)

can either argue the toss with him or save yourself the hassle, but spend on another test elsewhere

 

[jamesis2]

can't fail for that im a tester.

Do you know if there is some kind of 'appeal' against a fail??

 

[Daniel]

On the back of the Red refusal certificate.

 

[Tunst]

Thats bullshit we have had many car with Coilovers on and non have failed due to it being to firm...

 

[Hutchie]

if the spring is tooo firm, when it is jacked up the spring will be loose, this is a failure

 

[theduck]

Fun times

 

[Lozza-p]

WTF thats bull s&*t

 

[scotty2hotty81]

call VOSA or tell the garage your going to call them :evil:

 

[maynard]

pfft... you've been done over mate. take it back and complain if i was you. i watched my mot tester do my test - and there was no 'bounce' test. and he's legit too.

 

[Austin-182]

Lol failed for Being on its dish! Mine never faild and its loooow

 

[Austin-182]

if the spring is tooo firm, when it is jacked up the spring will be loose, this is a failure

Is that bad? Mine were lose and it didnt fail?

 

[TimR26]

Appeal to VOSA, sounds like garage to trying to have you for cost of labour for raising it up.

 

[Fred@BTM]

what a load of s**t, "bounce test" hahahahahaha

 

[D1CKY]

what a load of s**t, "bounce test" hahahahahaha

My thoughts exactly.

LMAO

Take car elsewhere job done :approve:

 

[jamesis2]

Spoken to k-tech and they say that it may be a bit to low! I shouldn't really fail for that but the test centre might be a bit picky. Anywho, 120mm seems to be the recommended height for it (start of the thread to the bottom locking nut)
Might have been nice if this sort of information was in the box when I got the suspension!!
Dig, dig round two with the mechanic & the test centre :dapprove:

 

[Gardus]

I'd like to see that mechanic do it on a Nissan GTR or a GT3...FAIL!

 

[Alastair.]

lol its not in the mot manual, suspension to hard, ring vosa get them to check and then they will pass it and the mot tester will get points on his licence

 

[Jonny1*2]

call VOSA and report the garage. I'd definately complain. I'd understand if the supension was too bouncy, suggesting shock problem, but too stiff, the guys haveing a bubble bath. It's amazing how many random things people fail cars for.

 

[Mike_08]

I always watch mine get done and have never seen him 'bounce' the car

 

[jamesis2]

I think they were being a bit anal with it, saying that it was too low for the rebound to work. Trouble is that the car is with a mechanic who takes it to an MOT centre, so I couldn't do anything... hence why so annoying! He's now raised it up 20mm and has now passed the MOT.
This all means I'll have to get the alignment re-done camber etc. which will cost another £81... My car is a money pit!

 

[Tunst]

The "Bounce Test" is just a simple way of findoing out if a shock absorber is nakerd any more than 3 bounces and the shocker is fucked. not many test stations do it as you can usually tell if its fucked when driving or observing, as said mate call VOSA..

 

[colossuss]

Or now its passed you could lower it back...

 

[Gardus]

Here in italy they do that test, but if springs and dampers are matched the cars doesn't rebound so it passes.

 

[Slammed172]

Lmao tbqfh.

Get on the telephone matey.

 

[Beef-Mc]

Bit late now since he's raised it.

 

[matty172cup]

lmao that garage would love my suspension its rock hard lol the k tec dampers are tuv approved so they should be fine id defo ring vosa and say wtfffffffffffffff is cracking off here

 

[Ralphizzle]

Wot? ROFLAO

Bonkers mate!

 

[andy_997]

thats stupid m8 my polo was slammed 110mm, it was that low that it only just passed the brake test as the subframe was ground out on the floor when it dropped into the rollers! An the suspension might as well have been welded up it was that hard haha. Not 2 mention the inch of stretch on the rear tires as well!
