Decided to order the springs, just to clarify this exact product code will work on 2 and 3way yeh?

Cheers

Thanks to Slicer and Malek for leading the way on this.
I'm glad it worked out for you!

I'm contemplating to change my current V3 to CS 3-way and I was wondering if I'll have any clearance issues like slicer

I'm not getting any rubbing on my v3 now, so I'm guessing it should be ok on the CS too?

19x9.5 +22 with 265/30 ad08r

any advise appreciated, thx!!

Maybe; I can't say for sure because I haven't had V3's. I do however think that the stack height of the clubsport springs are taller due to the fact that they have helper springs while the V3's do not. The combo of the helper spring and main spring pushes the perch lower and that's where the inner clearance issues occur. Again I can't say for sure where the V3 perch sits relative to the clubsport but I think you get a little more clearance with the V3.

Slicer,
Just the fronts? No need to change the rear? isnt it better to change all 4?

Talking about the Eibach conversion for Clubsport? Just the fronts to fit 275. Nothing to gain by doing rear springs as well, if that's even possible.

I'm about 5,000 mls in now, all good.

Great job!!

Do you still run spacers up front?

will this clear only et25 or will also work with et22?

Also are your rims 18x10 or 18x10.5?

Unsure if compatible with ET22. I'm 18x10 ET25.

et22 is 3mm further away from the inside as compared to et25. In other words it is less dependent upon inner clearance vs et25. So yes it will work on the inside with et22 wheels (outer clearance will be dependent upon your camber settings). I ran 275/35/18 BFG rival tires with 9.5 et22 and 10 et25 wheels without inner clearance issues (after the spring swap). I don't know about 10.5" wheels because I never ran them in the front and don't see any reason to do so.

The rear of an e92 M3 is not a coilover. The spring and shock are separate. The rear spring does not in any way affect tire clearance. I didn't change the front spring rate; I only went to a shorter spring in the same spring rate that came on the KW clubsports. There is absolutely nothing to be gained by changing the rear spring.

I see... thanks.....you also mentioned you didnt see any advantages going with swifts....can you specify?

A good combo would be a 7" spring along with a helper. Machine the adjuster from 61mm to 60mm to give you more spring choices.

I'm confused by this. The OEM KW spring is 170mm or 6.7". The whole point of doing the swap was to gain inner clearance by switching to a shorter 140mm spring. Your suggested spring would not help in that regard; in fact it would make it worse.

I outlined that in a previous post but it was deleted...

I don't like the length options that Swift offers. They make a 5" (127mm) spring and a 6" (152mm spring). I found that the 140mm spring was the perfect length. Long enough to allow enough travel and short enough to provide the inner clearance needed (while still using the standard KW helper spring). I'm sure that there is a way to make the Swift springs work (shorter helper spring). I went with the 140mm Eibach spring and it worked well.

That is the most ideal to maintain enough stroke in the spring. The helper can always be removed if needed. Anything shorter than a 6", coil bind is likely unless a very high rate is used.

Why would coil bind occur with a spring that has sufficient travel? As long as the shock hits the bump stop prior to the spring bottoming out then there is not an issue. Am I missing something?

The standard KW spring is 90nm / 170mm length with 92mm of travel

The Eibach spring is 90nm / 140mm length spring with 87mm of travel

You think there will be coil bind in this situation? I can tell you from my experience there is none. Now if I increased my ride height to a point that my spring bottoms prior to the shock then it would happen. But my understanding is that I only lost 5mm of spring travel by making this swap. Travel that I wasn't going to use because I don't run the car at OEM ride height. I was at least 40mm lower than OEM.

Still all good with my swap, and that includes Sebring last weekend.

The only way to be sure is to test and check. You may be okay with such a high rate spring. Springs should have enough rate to keep you off the bump stops as well. Hitting the bump stops constantly isn't ideal as spring rate goes to infinity and traction is lost at that corner.

You are giving the total stroke available. However, when installed and with the full weight of the vehicle on the springs, the stroke is much less than that.
