4th digit of chassis code is rear shocks
5th digit of chassi code is rear springs All your cars have factory rear comfort springs. In this case Dynamic Chassis of Coupe and Cabriolet is different. Equal commercial name, but is different. My C70 Coupe Dynamic Chassis have: Front orange factory springs Rear yellow factory springs (or vice-versa, because i see my old springs some days sgo to take misurement and i saw in a axle is orange and on another axle is yellow). In any case my C70 is a low car. Expecially at rear. Equal result with original and KYB. But some days ago is installed all new engine mounting Volvo Genuine. But comfort for my sensation was equal. Yesterday i replace the wheels: Ursa 7 x 16 205/55 16 91W Dunlop Sport Marxx RT DOT 2015 at end of life Changed for Canisto 7.5 X 17 225/45 19 94Y Good Year Eagle F1 Asymetric 5 DOT2021 Made in Germany (factory shipped) Confort is dramatically improved. In strange, normally 16 inch wheels have best comfort than 17 inch wheels (on some vehicle with equal wheels size of course) while this Asymetric 5 is extraordinary comfortable. But sensation may be influenced beacuse old tyre have 6 years and end of life and the actual tyres is new. Excuse me for very bad english. I'm italian.

Phone them, or use their online catalogue with your VIN number and you will get the right springs in the correct length and diameter for your car ie the spec will match the OEMs but be of much better quality than the originals. Take a look at this thread and you will find some useful info. https://www.volvoforums.org.uk/showt...=278271&page=2

The chassis on the cabriolet differs to that on the coupe, presumably because it's a heavier car.
The KYB springs don't work well on the cabriolet because they don't change the ride height uniformly - assuming the springs have the same compression rate. Stock Vs KYB 460-442= 4% reduction in ride height 430-400= 7% reduction in ride height On cabriolets with Dynamic suspension, only the front springs are Dynamic, all cars have the same rear spring. C70 Coupe with dynamic chassis, probably have Dynamic front and rear. I don't know what the spring lengths are for the factory lowered cars but I would suspect that they are a uniform reduction front to rear.

Hello I have bought Koni Special Active front struts for my C70.
I think to install it on front and leave rear new Sachs. Actually i not happy for the new Sachs front and rear (oredered time ago with some original spare part code of original). But i think is low quality struts. With new Koni Special Active i think comfort is dramatically best (i hope). But time ago i was read about not is really recessary to replace too the rear shocks. I ll try with only front struts. If comfort become excellent i not will buy rear shocks. If i ll notice problem at rear axle i ll buy too rear shocks. Is right? Or is necessary too equal rear shocks?

I changed my mind:
Buyed too rear Koni Special Active. In next weeks i'll have Koni Special Active front + rear. Now i need to select best bump stop for confort. Actual was ordered from Polar Parts. I think is low quality product.

The LESJÖFORS are the OEM spec and really have the car driving/handling well; the rear is significantly lifted from when I bought it, there's no steering indecisive wandering or tramlining - but then it has still only got 41K miles on it from new!
