    Hello everyone, was thinking of purchasing those new Bilsteins. B/C my tires are too close to the strut perch. 245/65/17's. Keep hearing a lot of people having issues with them bending. Most of those guys have the stiffer eibachs or ATP's and still have the sway bar links hooked up. Was wondering if I would have a better chance of not bending them if I keep the stock softer springs and maybe even disconnect the sway bar links ? I don't really do a lot of high speed cornering or anything. Also hear there's and Italian strut out there too but good luck trying to get them here.

    Thoughts anyone ?

    ATP springs did not make my Renegade ride any stiffer.

    Replacing the spring does not raise the lower spring perch to give you the clearance that you are looking for.

    I went with Supreme Engineering Technologies Jeep Renegade Wheel Spacers 5x110 Hub Centric | 65.1mm Center Bore 1" Inch Thick or 25mm | 12x1.25 Studs (for example) anything wider will rub on the fender liner at 3/4 turn.

    Thoughts: A 1 inch spacer will widen your stance, look better and allow to clear the spring perch at a fraction of the cost of replacing struts, or springs.

    Yes true, "Replacing the spring does not raise the lower spring perch to give you the clearance that you are looking for."
    But the Bilstein "strut", not spring, does. It has the spring perch located just a little higher than the factory strut which also gives you the clearance needed. Interesting that you said the ATP springs did not make it any stiffer. Do you have the 4.0 kit or just the springs ? I'm currently running the ATP 2.0 with 20.mm spacers. And it just barely clears now. Just wanted a little more breathing room. Might consider adding the springs if the ride is not much stiffer.

    I used the AVID 2.5 lift with the ATP springs (I wanted the red springs).

    I did hear, on more then 1 occasion that the Bilstein 5100 have weak lower mounts and are prone to bend. I wouldn't use then just for the reliability factor.
    Don't get me wrong, I use the Bilstein B6's on my other vehicles and will use them all day long; just not the 5100's.

    If you are clearing the lower spring perch with 20mm spacers, why change? The top of the tire doesn't flex, so it can't/shouldn't touch.

    True. . . Maybe I'll leave that and just change to the red springs too. So with the Avid 2.5 and the ATP springs no problem with the CV joints or the boots ? Also not really much stiffer a ride ?

    Thanks in Advance

    With the addition of the springs, you will have to modify the lower part of the stock strut so that the half shaft clears. The Bilstein B6 does not have the lip that the oem strut does, so the B6 does not need to be modified/clearanced.

    With a 4 inch lift you will feel some vibration under load (hard acceleration) from the front CV joints because of the angle.
    I had a turbo, 262 HP to the wheels, drove it hard for 10K without any reliability issues.
