After 25 years of sitting on dunlops I felt I needed to replace them on my MK1 850 with new.

 

Obviously I read lots of posts on a number of forums before buying them early last year but probably bought on price as I felt that the 2 "genuine" reproductions were probably equally as good.

 

So with the lock down I've finished the birthday on the rear and am half way through the front giving it a disc upgrade as well.

 

When I put this car together 25 years ago I lowered it an inch by trimming the trumpets.

 

The rear is some what high which reading other forum topics is probably right with these "genuine one and only std cones" which I've ignored as I understand it should settle.

 

However I can't slip the upper bump stop into the fronts unless I compress the cone and then it only just goes in, which is alarming.

 

So I'm looking for some advice from those in the know

 

Will these cones settle?

or

Do I need to buy a set from the other one and only std genuine cone 93mm supplier - which will leave me feeling a little pissed as I was hoping to use the funds for a new set of wheels & boots.

or

Should I ditch the trumpets for Hi-Lo's - again not in my budget 

or

Should I trim a little more off my trumpets - how far can I go

 

Many thanks

Carl

Doughnuts / cones settle, fact of life.............I have never known any, that overtime, didn't settle

 

I wouldn't cut any more off the trumpet.

 

I can't get my head round your "upper bump stop" problem.  New doughnuts result in more pressure pushing the top wishbone down, which makes more room for the bump stop.

I'd imagine he's talking about the rebound stops.

Do you mean the little bump stops on the 'L' shaped metal mounts?

Those are fitted when there is weight on the wheel (ie. the wheel is not in the air).

Yes - the one that slips in under the top arm, sorry yes the rebound stop and with the car on it's wheels but it is just one side down at the mo

Take it for a gentle drive, Carl, and the suspension will settle enough to get the rebound stop in.

Thanks for the replies - just had few minutes in the garage jacking the one side up and down a few times, fairly happy now, there seems to be a reasonable amount of travel in the suspension and the rebound rubber has eased in nicely with space to spare.

 

I probably should have been a bit more aggressive with the jack earlier!
