Solution for KW Clubsport Inner Wheel Clearance Issues

BMWSpeedFreek · 01-12-2021, 02:24 PM

Ok, I have been able to remove 3 of the 8 T45 camber plate screws using an impact wrench - the other 5 won’t budge.

Any ideas?

They should not be very tight since the torque spec is 17 lbs-ft. If it's an electric impact try charging the battery. Sometimes, with bolts in a circular pattern, it helps to break them loose (1/4 turn) one at a time before backing them out. By design, the threaded holes in the mount are not exactly center-aligned with the camber plate bolt holes. This may be putting pressure on the other bolts. That's all I got.

Thanks chalbe - just tried it with a fully-charged battery.
No go.

They feel like they've been tightened to 20+ lb-ft ...

Also having a dickens of a time getting enough of a grip on the top plate to even work with my hand torque-wrench...what did you do to prevent the top plate from trying to rotate with the 17 lb-ft of torque?

Other than trying some penetrating fluid (Is WD40 ok?), I am fearful of stripping the T45 bolt heads trying to undo them.

So...asking for a friend - has anyone ever had to replace one of these KW torx bolts? KW USA contact info? cost? torx bolt spec? would be greatly appreciated...by my friend. j/j, just in case...

Thanks again to all for your advice!!

Put the bolts back on that are easily removed. Tighten them to take some of the load off the most stubborn bolt. Then try again. This sometimes helps. Penetrating oil if needed. You will want to remove the oil prior to re-install to make sure you don't over-tighten.

Yea, I stripped a couple when trying to loosen some that were over-torqued. Then I just impacted them out easily.

fsmtnbiker gave me the replacement bolt specs: McMaster.com torx pack of 10: 90236A169

I bought a bag of these a while back and would highly recommend. They have been invaluable to have as spares when one gets inevitably stripped after multiple alignments or to have as replacements when you remove the kit to get rebuilt eventually.

I would do what slicer wrote. You can use the 10mm hex on the piston shaft as the counter. If you are working on the floor, you can position the coilover so that the ground holds the counter, and you can focus your energy on breaking loose the torx bolts.

I am remembering now that removing these bolts was not as easy as it seemed. Stick with it, you will get it.

BMWSpeedFreek · 01-20-2021, 06:51 PM

Ok, again guys - Thanks!!

Finally got the last ones removed using a dash of liquid wrench, retightening the ones I had loosened, a little patience, and then they finally gave way with no damage to the torx heads.

Springs now swapped out with Eibach 5.5". Next step is once I can confidently torque the 22mm centre nut to required spec*, to do it with blue threadlocker. Then the torx screws to 'snug' (where 'snug' = <17lb-ft) in preparation for the install and alignment.

Cheers guys!

*I plan to use the 50.1Nm/37lb-ft spec.

I'm currently getting this work done and there is not enough clearance with Nitto NT01s, 275s without a spacer. Any other solutions you guys may have besides going back to stock KW CS springs and removing the helper, if that even works.

Helpers really don't do much, I didn't want to remove mine either but after it's been out for a couple events, they're fine. Very very rarely will two front wheels come off the ground.

Going back to the stock spring and removing the helper will put you in the exact same position as you are now. The OE spring is 170mm, presumably you changed to a 140mm. That's 30mm of difference compared to the stack height of the helper which is likely about the same (if not less).

The shop is saying they can't use the eibach spring it's too short with no helper?

That could be true. It depends on your ride height. You may run out of threads for the spring perch. However I have used 140mm springs on other suspension kits without issues (without helper).

I know it's an old thread but it was such an awesome solution for the E90/2 platform. Wonder if slicer or anyone knows if the same spring swap can be done on F80/2 platform. I'm anticipating a clearance issue between my KW Clubsport and the 10" wide ET25 front wheels that I'm planning to get for my F80.

The standard front springs come with KW Clubsport 2-Way for F80 is 80nm / 170mm.

Thanks.

Yes, the exact same thing can be done on F8x, e46, etc.

By using the exact same 90nm/140mm Eibach springs to clear the 10" wide ET25 wheels without the need of any spacer on a F80/2? Any concern on the tires?

I'm trying to put these at the front on my F80:

F: 19" x 10" ET25 | 275/30-19 Falkens RT660 | Overall Diameter: 25.6" | Tread Width: 10.2" | Section Width: 11.1"

I would consider going with 265/35/19 front tires but you can make 275/30/19 work. Success is not guaranteed because fit is dependent on the tire's real-world dimensions and your actual spring perch location (ride height setting). The lower the car is, the lower the spring perch sits and the closer it is to tire. I would have a spacer on hand in case it doesn't fit. I typically spec my wheels at a lower offset to avoid this issue. However the spring swap is still a worthy change because it can allow you to fit a 10.5" front wheel.

Super thankful for Slicer making this thread. My front inner perch clearance issues have been solved by using a shorter spring.

Just want to mention a new (but also expensive) solution from ST Suspensions.
PART-NO.: 68517002

https://www.stsuspensions.com/catalo...091-5-1-7-8998

The kit comes with a pair of 140mm KW springs and a new set of helper springs.
It may not be the cheapest solution, but it seems to be the most "complete" solution.

Thanks for sharing this! I just installed my ST XTA and have 275/35/18 Conti ECS up front on a 10" wheel with -3 camber and 5 mm spacers with no clearance issues. However, with all that being said what would be the reason to go with the ST spring you're mentioning as opposed to a Swift or Eibach spring? I'm basically seeing if there is any room for improvement over the included ST springs.

Good question - I think it boils down to brand preference. If you need a shorter spring setup and want to keep it in the KW/ST brand then this would be an option as it comes complete with a new set of helper springs and intermediate rings. It takes away some of the guess work and trial and error that one might experience when deciding on a shorter spring for more clearance.

OK got it, thanks!

Bon F80 · 05-18-2022, 09:58 AM

May I know please if anyone has done the main spring swap on KW Clubsport using H&R Springs? I can't seem to find Eibach springs that I need in stock, I may be able to get H&R Springs in a shorter time frame.

My main question is if you had to machine the KW spring perch/collar to fit the H&R Springs?
