Same Suspension as 335?

[Motorsports_3]

I might have a deal working out for prototyping a set of coilovers. The company makes suspension for the 1 series hatchback, and for the 335 along with other cars.
From what I know, 335 suspension should bolt right up right? I am also going with custom spring rates. Does anyone have an idea what they would reccomend. It should be higher than a 335 correct? sorry for my newbie questions. Im a little new on all of this suspensions specifics.

Im pretty sure it is the same as the 335, but no one here knows? Im talking about mounting points, not the actual part numbers.

Also I was thinking of getting a spring rate around 10, does that seem good.

yes it's the same as the 335i. and what do you men by spring rat of 10. usually spring rates are in lb/in. and I'd suggest 350lbs/in all around some people go more but 350 seems to be a good starting point I guess it all depends on what your going to use the car for and how you want it to ride.

Thank you. Some people use numbers to signify the spring rate. 350/in is around a 6 as 6 is 336/in. Is isnt that kind of soft. I want the car to be stiff, not like a track car, but the H&Rs are too soft. Maybe like 400/in, 450/in. Do you know what the H&R sport springs are?

I ran 440 lb/in front and 550 lb/in rear Ground Control coilovers on my E36 M3 and they felt pretty stiff on the street even with shocks set at full soft, not excruciating, but my wife sure didn't care for the ride. Handling was certainly awesome though!

I wow that seems stiff. LOL. I think I am going to go with like a 400/inch. If that is bad I might change it.

Many E36 autocrosses and road racers run spring rates in the range of 600-700 front and 900-1000 rear. Now that's STIFF!
