Bilstien bump stop removal question ?

[retvert325]

I am installing bil. sports and H&R race springs on my 325i

and I see people have removed part of the bump stop to keep
the struts from bottoming out .

How much of the stop do I remove ?

Thanks

half is typical

I always do 1/3.

Remove less to start. You can always cut more. Putting it back.. well..

I heard through another forum member that on the sports I don't have to remove any of the bump stop because the sport strut is shortened to work with lower springs . If I had the HD's they would need the bump stop partially removed .

???? any thoughts on this .

^ The sports have a shorter extended length (less droop) than HD.

What you are doing by cutting the bump stop is allowing more up travel (compression) before the shock hits the bump stop.

1" of bump stop. No more.
