Lowering...

The springs we are fairly sure you must have had 50mm front rather than the 70's. However we were finding on some cars the front springs were not always lowering as much as they should so some slight changes have been made.

What will you be doing to replace the wrongly made springs you supplied then now you have found a problem ?
Did you carry out any development before selling them in the first place or is it just a case of flogging people anything and hoping you can get away with it ?

Sorry about hijacking the thread. I've got a standard 940 Celebration, The shocks are springs are all original and kinda tired. I'm OK with the comfortable set up it has but would not mind it a little firmer.
What do you guys recommend if I wanted to bring it to the "sport" spec (15mm lower) with a nivomat delete?

Well Steve, first step with designing springs is first to study the original springs. Then a fair bif of calculation is needed to work out motion ratios and desired spring rates. Corner weights need to be measured (bear in mind this can vary with options, fuel and allowance for loading) and you can then work out from there the dimensions for the springs.
Next step is test fitting and road testing and revisions if needed.
As products get more and more use things can come to light resulting in a revision being deemed beneficial and that is what has happened here.


As to how those with issues have been resolved. In most cases the springs have worked as intended. A few have not and the solution has not been the same in every case

Yeah that was one of the issues, the other being that the shocks would not seat inside the retaining nut on the top because there was no 'neck' to the top of the shocks. So you basically had to eyeball the shock to a central position as you were tightening the nut down. Like I said, once it was all tightened, it wasn't going anywhere. But I'd expect the manufacturing process for the nut and or the shock to be modified to overcome this problem.

My only gripe with the actual functionality of the set-up is that the rear springs could be stiffer. The springs didn't feel that much different than the original nivomat springs.

Sorry you must have forgotten I have seen previous examples of how you have done things, I will have to dig out the LPG tank installation photo again.

Go for the BC BR series kit...you will never look back.

Probably nothing, he's very good at that.

Hi guys - I'm a new 940 owner having recently purchased a 2.0 S. I know its not a turbo or even mildly sporty, and I'm torn between keeping it standard going with the classic look, and lowering it a bit to make it look a bit cooler.

Anyway, I'm on a budget (to keep the wife happy) and was wondering what your opinions are on the Kilen -40/-25 springs, and if you have any pictures of them fitted?

Also, do you NEED to replace the dampers too when fitting these?

Kilen is a subsidiary of Lesjofors, one of the OE suppliers to Volvo so they should be good springs.
I do happen to know of some coil-overs not far from you that might be for sale, not sure if the owner of them has disposed of them or retained them but it's the starter of this thread here :

To answer your question about renewing the shocks when changing the springs, it's definitely advisable, yes. Look on fleabay for normal shocks that will fit 740 and 940 Volvos, should be able to pick them up relatively cheaply. I changed the springs and shocks on all 4 corners of my 760 for about £125 a couple of years back, the shocks were KYB as well, springs if memory serves were Suplex, again a subsidiary of a well known company!

Good luck with it and errr....... oh yeah, welcome aboard!

Thank you for the advice. Is the recommendation to replace the shocks based on the thinking that the current ones are potentially 25 years old and not performing at their best?
