Very interested! Have any pictures? Is the drop the same, more, less ?

2021 M3 Competition X-Drive AST install in the bag. M3 looks, drives and feels absolutely fantastic. Drop is identical to non X-Drive.

Vehicle: 2021 X-Drive BMW M3 Competition
Suspension: AST Lowering Springs
Tires: Pirelli P Zero, 275/35-19 (F), 295/20-20 (R)
Spacers: Macht Schnell Competition Spacers: 10mm (F), 12mm (R)

Thanks Tom! Looks great. Lmk when the new orders come in and I’ll get you payment !

BTW I already bought a 12.5/15 spacer setup. Looks like those may still work. I’m thoughts on that?

We'll have the BMC filters on Friday, I'll give you a ring what they arrive.

12.5/15 should be ok, but there may be a slight bit of running on full lock until it "autotrims" (rubs inner fender liner). Otherwise, step down to 10mm.

Any idea what the stock rates are vs AST rates ?
Stiffer or softer than H&R etc.
thanks.

H&R is known to have a very stiff ride on past applications, we typically avoid these unless there is no other option. No published spring rates for either H&R or AST, sorry.

As for H&R, I wonder if that's a byproduct of an actual stiffer spring rate of the coil or more contact with the bump stop, as a byproduct of increased lowering.

Springs and HAS on EDC is like a mouse trap for me. I like the car stock , wouldn't mind a slightly stiffer rate with a slightly lowered front.

All to often lowering springs are sitting on factory bump stops at static ride height.

Dinan's philosophy with the HAS on the F80 seemed to be spot on. The key here was following the suggested ride night in the manual and measuring the shock body to bump stop clearances with a tie wrap on the shock shaft.

If EAS can provide this data on the AST's that would be helpful for those who may be concerned with those clearances which could artificially induce more understeer or oversteer based on front to rear clearances.

Typically, lowering springs will be slightly stiffer to account for the smaller travel amount. It's up to manufacturers to decide up on how much.

On E92/F80, the bump stop is used as part of the dampening process. There's some white papers online posted about this and most likely the same rule applies to G8x.

Anyone have a range for what this should cost to have someone install? My first quote was $1150.

Heck I'll rent a lift and do it myself at that rate.

[mattssi]

I've gotten 800-1100, its ridiculous. Best deal is Tom @ EAS which is why I'm considering making a 10 hour trip out of it. Plus he's done it before.

Shops that are quoting those prices likely have not installed a set yet and are using book time to quote rates. Sometimes book time doesn't apply in the real world, but most times it's pretty close. Hopefully, real time is charged once all said and done.

Shops rates vary. Typical install time is ~3 hours, slightly longer for X-Drive and ensures all fasteners are torqued properly and not just air-ratcheted into place.

Tom is a bit out of my commute range. Ha.

I have a feeling I'm going to get a lot of quotes like this... I might try and DIY, even if I have to rent a lift myself. I've done springs on other cars, I was just was looking to hit the easy button.

Here's the folder on our Flickr site for the X-Drive install, there's more pictures in there that wasn't posted - they will help in installing:

Yeah, that did help me know that for AWD I'll have to pull the axle (do you recall the hub nut size?). Knowing that upfront saves some head scratching time for sure! I had to do this for a Jetta recently as well, so I get the drill. On that car it was rather easy once we did that.

Rears looks the same and besides the struggles I hear in getting the bolt and holes to line up it's very straight forward.

Thanks again for sharing those!

[mattssi]

With the ASTs, do you do an alignment right away or should you wait a bit?

Typically 1 week driving time is good to allow everything to settle properly, and in case you need to go back in that area again.

Correct. And the most important part of this process is "when" the engagement takes place.

BMW calls the bump stops "supplemental shocks absorbers".

Does the AST kit provide bump stops ?

Thanks Tom!

Original bump stops are retained.

this looks good! what the pricing on this?

Should be springs + 2.5 - 3 hour labor max

Man this makes waiting for my SG M3 even harder... got the AST springs and FC spacers just need the car LOL

AST Lowering Springs are manufactured from a premium high tensile chromium-silicone wire which is handpicked by AST engineers for its quality and metal consistency. Each spring is cold wound and then heat treated to increase hardness and reduce internal stresses present after winding. Each spring is then individually shot peened, phosphate treated and then powder coated to outlast even the life of the vehicle.

AST suspension lowering springs will lower that center of gravity without giving in a lot of the comfort you are used to with the OEM springs. The lowering springs are a direct replacement of the OEM springs and have been developed especially for each vehicle specific. Made out of the best material on the best Wafios coiling machines available.

Features
- Drop of 30mm up front, 15mm in rear
- Developed and tested to work flawless with stock dampers
- Progressive design for the best lowering vs performance
- Cold coiled
- Premium high tensile chromium-silicone wire
- Powdercoated finish
- Lifetime warranty

G82 M4 fitment coming soon.

Do you have the M4 Springs in stock?
