I got my Gmax -35 supersport kit this morning, and only then did I find out you have to take at least 20mm out of the original bump stops! I haven't seen how the bump stops go on, but is it just a case of pulling them out and cutting 20mm off, or should I buy uprated ones? If so, anyone got any rough costs? I assume this adds another 20mm to the lowering procedure, which would explain why so many ppl say the 35mm kit seems so low!

PICS AT BOTTOM OF THREAD

[phils_wicked]

dunno if cutting them makes the car lower, since the car should'nt be sitting on the bumpstops anyway

but yea all u do is pull off the bumpstop and chop of 20mm, breadknife worked wonders lol

*edited id put should "instead" of "should'nt" *

[heeman10]

Surely if it's sitting on the bumpstops and you cut 20mm off, it'll sit another 20mm lower? I've heard people saying uprating bumpstops is a good idea though...anyone?

[wywywywy]

Hi... what exactly is a "bumpstop"?
Thanks.

[AdrianFRST]

Bumpstops are hard rubber bungs that act as suspension limiters. The idea is if you hit a really hard bump and the shock compresses as far as it can go it hits the rubber rather than the metal parts of the shock colliding.

Same principal as those rubber door stops you get in houses to stop you banging doors on walls or shelves etc.

With the car's standard ride height they tent to be somewhat generous in size, which means you quite often end up hitting them if the car's lowered. The spring mfrs advice you to cut them down to avoid this. Lopping them in half will still leave more than enough.

As the car is not resting on them when it's not moving, they don't affect ride height at all. That is unless it's *really* low, hence the term "get it on the bumpstops".

Nice explanation. I dont remember seeing bump stops on my old Spax suspension or on my new coilovers

[beanyfrst]

so you mean you dont need bump stops -stoned-

[heeman10]

Too right Ade, I have no idea why I was thinking it was sitting on the bumpstops I'll chop mine about a bit then, thanks. Will see what they look like when I take them off. Insurers aren't being very nice about it. They want a professional engineer's report of the "work" that was "carried out", on a proper letterhead. Shame I can't just tell them what I'm doing

[heeman10]

Yeah you need bumpstops, otherwise you'll get some jarring shocks through the chassis if you bottom out in a hole/sudden bump/landing after a hump backed bridge in Cumbria about 25 miles from me

[Stoned]

so you mean you dont need bump stops -stoned-

Not really, I just dont remember seeing them

This was my old Spax suspension as taken off my car



And these are my new coilovers on the right



What part is the bump stop then?

[AdrianFRST]

On the Spax it's the rubber bit between the gold coloured top mount and the shock boot.

On the H&R they'll be under the boots themselves.

[heeman10]

I've only looked at mine for a few seconds, and tucked them back under my bed, but I'm sure my fronts had the bumpstops in the same place as the Spax above. So why are they telling me to reduce my original bumpstops if they're already on the shockers? Do I need to reduce the GMax ones? Perhaps I should just call Jay to get things straight...

[fizxr2i1649]

think u can by some spax bumpstops they cost about £15 i think
if that helps if not sorry



but thats wot i think

[heeman10]

PM from Jay sorted it all. Bump stops on Gmax kit can be used at the front, and (I couldn't remember if there were any provided on the Gmax rears) on the rear, the original stops need to be sawn down by 20mm and put on the new shocks Sorted

[Escort Cos]

The bump stop just slides onto the suspension rod.

When you look at the bump stop it looks like a bumpy bit of rubber, cut the 2 bumps off the bottom and that is the same as 20mm.

[heeman10]

Cheers

[Maff Si]

The bump stop is number 4 on this diagram


On the rear the bump stop is part of the damper itself

[heeman10]

Ok, I now have a good digicam, and the bottom picture shows the front strut (right) and rear strut (left). I believe the foamy stuff at the top of the front strut is the Gmax bumpstop which is what I need. Is the plastic/nylon thing on the end of the rear strut the bumpstop? Do I need to remove any material from it, or is that what Gmax put on to be used as the new bumpstop? It seems a bit hard to be a bumpstop, but having never seen the Fiesta bumpstops, I wouldn't know what to expect. Anyone got any bright ideas?!

[voorhas]

I'd say the front strut is the one on your other left Seriously now, the front is on the right and the back is on the left. The plastic type thing u see on the front isn't the bump stop... if anything, it would be a bump enhancer Mr. Haynes calls it a "dust cover". I'd advise you on getting new bumpstops from Ford or elsewhere because the fronts have the annoying tendency to be ripped to bits after a few years use.

The back one apparently already has the bumpstop fitted to it... but I'd advise you on measuring the standard one and comparing it to the new to see if its short enough for the job, just in case they're complete muppets.

[voorhas]

Oh, and congrats on the new cam... it works a treat!

Goncalo D.

[heeman10]

Doh! Thanks for the left/right correction...I would've put them on the right ends of the car anyway!! I'll get hold of front bumpstops then, and will make sure I check those rear lengths Cheers for that.

And I'm enjoying this camera very much, it's quality! Take a few 15sec vid clips too

[Brian]

WOAH! I'm confused about the old suspension!!

I bought GMAX lowering springs and as i remember had to cut the front bumpstops, but are there bumpstops at the back? As i can't remember, i thought the strut was 'sealed'.

Do you have the proper kit (40-FO-12)? And do they give you new bumpstops, which for , front or back?
