This Post is NOT related to ANY Firm directly but rather is a General Heads Up to ALL You Folks out There (Even Those with Stock Suspension).

It has come to My Attention that Some are trimming Their Bump Stops without consulting the Supplier (BMW, GC, TCK, &c). DON'T DO THIS!!!!

Trimming a BumpStop past It's needed/design Length - typically the supplied Length (unless SPECIFICALLY instructed in the Supplier's Installation Directions) - IS STUPID (dare I say Retarded in an A$$Hole sorta way)!!!

I have always replied to Persons, Here and in Private, NOT to do This without consulting the Supplier and frankly, NEVER imagined AnyOne would do so. Even in Cases where I have sold the Suspension, I have the Customer contact Jay, Bilstein, TC, &c directly and prior to trimming.

Bad Things that can happen to Folks so doing include but are NOT limited to:

1. Damper can exceed Its Max compression and sustain terminal Damage - and possibly loss of Driver control. Results include Suspension getting immediately solid and causing One to go off the Road/Track - maybe even getting an innocent Party killed.

2. Springs can compress sufficient to coilbind (causing the same loss of control) and possibly even change Diametre and Length of Spring.


PLEASE, PLEASE do NOT do This without consulting the Supplier first.

It is NOT meant as a Statement on Suppliers but rather Customers making Bad Mods without Suppliers' Consent nor Advice.

...d/a Konis, 450lb/6in springs. Front is dropped, hub to fender, 13 3/8 on driver's side, 13 1/4 on passenger side.

Seems okay after eight months...did I cross the line?

Thanks.

point since the bumpstop compresses very easily under load. [Oops!] such, seems like the issues you raise will occur regardless of whether the bumpstop is trimmed, since i do not see how trimming the bumpstop changes the overall travel of the shock.

amount is factored into the size chosen, right? The purpose it to keep the piston from bottoming out in the shock and breaking it. If you trim the bumpstop too far, it allows the shock piston to hit the bottom and blow the shock.

Dan's point is that most bumpstops have a little extra safety margin and that it is possible to cut a bit off to gain extra travel. How much can be cut off safely is info that should come from a supplier, not an internet buddy. There are legit safety an monetary concerns here.<p align="center"><a href="http://www.doubledracing.net">

no hood.

Should pose no problems in Boston.

Also, you need to take more of your pics at sobe, if you know what I mean. Less ships, more hips.

Watcha sayin, DD? I mean, look:

You can't see it, sure, but he has BOTH PAWS on the wheel. How can one go wrong with man's best internet buddy?

BTW, no discussion of trimming is complete without Stoney weighing in:

http://bimmer.roadfly.org/bmw/forums/m-lounge/5468589-4.html

I'm staying trimmed until he says otherwise.

whether My Customers or from Some Other Shop. It puts Me and Vendors who want to help Customers in a bad Position when a Customer makes unauthorized and ill advised Modifications to Parts integral to a SYSTEM'S Design.

Why should the Supplier want to warranty SomeThing that was ruined by an unauthorized and ill advised Modification? Is This fair to the Supplier? Is It fair to the Dealer? Is It fair to Consumers who need to pay higher Prices in order to cover unreasonable Claims?

For Example, If I change My Diff to a 4,5 and the Rear End fails, should I even ask BMW to warantee It, let alone be upset if They reasonably say "NO"?

We, as Consumers need to consider such Things when We Bi+ch at Suppliers. After all, They (Suppliers and Dealers) have a right to make an honest Living - which is hard if People expect Them to pay for Their (the Customer's) Mistakes. Also, We NEED Suppliers and Dealers to be able to make Profit in order to stay in Business and feed Our Passion.

...just curious if you already went over this subject with JM before trimming yours for more travel.

Everyone's setup/applications are a bit different, so what Dan says makes perfect sense. Since you are pretty thorough in checking things out, however, just wondering what your process was, and weather you are alarmed as Dan is making me.

Will call JM, however, just to confirm I didn't do anything inadvisable in my specific case.

Thanks.
