Suplex M Sport Springs

[Rakey78]

Could someone tell me the part numbers for the Suplex M Sport springs please as switching to Bilstein B4's and want the m sport springs as 30mm is too low for the roads near me so 15mm will do.

I cant seem to find the threads I was looking at. I think fronts were 06248 but cant remember rears.

I've emailed Suplex today asking the same question.

My research suggests:

Front =06248 (manual transmission)
Rear 06231

mines a 3.0 e85

 

[Rakey78]

Awesome, thank you. I did save it somewhere but cant find it now. At least the fronts were right

Mines the 2.2.

Guessing these springs will give the 15mm drop?

In theory you'd need 6230 if your car is a 2.2 manual (with options). I have a pair of 6230 springs you could have for next to nothing. I have fitted them in January and covered maybe 150 miles since. I have ordered 6231 but got the 6230 by mistake and only realised after fitting so no chance to return.

Let me know if you're interested. I know people are (correctly) unsure about used springs, but I'm not sure if these really qualify as "used"

What is meant by "options"? I'm struggling to think of something that would mean fitting different rear springs

Correct. That’s for the 3.0.

I think it’s about the overall weight off the vehicle. Someone here found a BMW software that changed the OEM spring part number depending which items you selected as fitted to the car.

I'm assuming "opts" means "optional M Sport suspension".

The 3.0 pre-facelift all came with it whereas the rest of the range had it as an option which supported that.

That sounds sensible, but then I noticed that the above table is titled 'vehicles with M Sport suspension', and only the rear springs differ with the 'options'. So I'm still puzzled...
