I cut half a coil from the top. The bottom of the spring is the thicker part and would make sense to cut from there so you don't diminish the progressive rate of the spring, however there is taper to the diameter at the bottom where it meets the spring pad and I didn't want to risk it not reseating if I cut the bottom.

Did you notice much different in the ride ? Would I have to cut 1/2 or could I just cut 1/3 .

Really didn't notice any difference in ride. 1/2 of a spring loop lowered my car by about 1/2". Its a pretty minor surgery, besides the car sitting lower I doubt you'll notice any other differences.

FYI/Caveat Emptor - we are 100% NOT endorsing or recommending cutting the springs.

The AWD Factory springs are shorter than the 2WD. For those of you who do want the lower front you can probably fit the AWD front springs.

Stuart -

I am interested to know if there was any validation done on the AP Springs to determine durability? I come from the Automotive world in Detroit, MI and I'm always fascinated by aftermarket parts for cars that never need to see PPAP. (Production Part Approval Process)

I have heard that King Springs in Australia uses X5K steel to produce springs and wondered if they supply for you. Obviously, you don't need to answer that - I am just wondering about the process used and if its similar?

Are these powder coated? or painted?
After the assumed Peel Taper/Heat/Cool/Harden/Temper

Also if you could shoot me a quote for a set for a 2015 Type-R RWD I would appreciate it. I'm in the market for a set. Also what is the turnaround time when I order?

Thank you!

Chip
Michigan

Are we talking about cutting the Jaguar factory springs here or the VAP springs?

If you guys are cutting the factory springs, then could I do the same with my SVR? I would love to lower it about 1/3" in the front and 1/2" in the rear, I just find that the VAP, H&R springs look too low for me (personal taste) and I'd far rather just lower the car 1/3-1/2" maximum, hence considering the KW HAS kit, but if it is safe to cut 1/2 coil from the factory springs then that seems like a plan.

I assume its best to cut from top of spring?

I cut the VAP spring, but I don't see why you couldn't cut the factory one. The spring perch rotates, so there is no concern with having to cut a full coil loop, which is required on some vehicles. Also, I recommend you cut with a simple grinder, cutting with a torch can create enough heat to alter the spring.

Well as I only want to lower by upto 1/2" maximum I'd probably just remove half a coil.

Yes, but thats the problem with my method - no formula to know how much you cut vs. how much drop. Clearly you can't uncut, so small increments would be best.

If you can get under the car to measure the compressed height of the spring, you could avoid a lot of trial and error work:
Hu2=Hu1 x (Hc1-0.5") / Hc1
Where Hu1 and Hc1 are the height of the uncompressed and compressed OEM spring, respectively, and Hu2 is the height to which you would want to cut the height of the uncompressed spring.

Looks like you got the off-road springs.

I would suggest returning the Eibachs as they don’t fit right, and buy a properly engineered spring set from VAP or H&R. Cut springs run the risk of not sitting properly in the seats and potentially causing handling issues as they shift.

I live in Madrid, Spain, and Eibach suggested that I send the springs to Germany to analyze what happened. Weeks without a car, maybe months? So I did not accept and I have 4 front and 2 rear springs without mounting and without much money spent on assemblies ... It seems that the option to cut springs has not gone bad here, right?

From so much put and remove springs a suspension broke and as the car has 33,000 miles I bought 4 Bilstein B4 ...

I seem to remember one other person thinking about cutting springs, but I don’t remember if they ever reported back after the installation.

It worked well for me on trimming the VAP springs to get fine tuning on the font height. Since they sent you a 2nd set, you have extra springs so it costs you nothing but time to try. I'd cut 3/4 of a coil and see what that it does for you. Still, can't imagine what is going on where the Eibach's raised the front of your car...

Rear VAP AP Lowering Springs - AWD



Both VAP AP Lowering Springs - AWD
Do you know what your ride height is front and rear with these springs?

On mine it was about 360mm front and 348mm rear measuring from wheel center to fender edge vertically.
