Springs rates - SE vs M sport

[DaveD]

Guys

Does anyone know what the spring rates are for the SE and M sport springs on a 3.0si coupe?

I’m SE at the moment with B6 shocks. The rear of my car does look a bit high but front is ok so wondering about impact of putting M springs on the back. The rear of the car is pretty compliant and springs soft, so feels like it could work. I understand that firmer rear springs could make the car more oversteer prone, but not sure of this would actually just balance out the built in understeer?

Let me know if this is completely bonkers!

Bumpety bump... appreciate any views from those more knowledgable than I!

How much difference does forming up the rear spring rate vs the front make to handling?

Dave - I am not sure about different springs on front and rear - sounds wrong - but on the basis rear springs are an easy change it might be worth a punt to see what it feels like.

I run B6 shocks with Msport equivalent springs (Suplex) on all four corners and it is hard, but the handling is great - tbh the change in shocks after 86k miles probably masked any spring differences in any event. BTW B6 shocks with Msport springs is not recommended by Bilstein - but I havent had any issue with it - and they are only 15mm lower than SE anyway - I suspect it might be a different story if you opted for a bigger drop - say 30mm.

Thanks mate. Appreciate your thoughts.

Noted on the b6s - I think they can take a 30mm drop vs SE height which is why I’d only look a m sport springs. Want to keep the travel!

I find the front is definitely firmer than the rear currently - all that engine weight on the fronts. Definitely easier to bounce the rear of the car by hand.
