Hi Guys,

Just got delivery of the H&R swaybar kit (front & rear) and the box did not contain new mounting hardware and bushings. Does anyone know if the H&R kit reuse the stock mounting hardware and bushings? Front is 27mm and rear is 23mm.

Thanks, JE

That doesn't sound right. The hardware (4 lock nuts) would be easy enough to buy at a local hardware store, but the rubber bushings would have to be specific to the bar i.e., the ID of the bushing would be larger than stock to accomodate larger H&R bar diameter, but outer dimensions of the bushing would be same as stock.

I would contact the vendor/manufacturer.

As per the vendor the original hardware and bushings are to be reused and the difference in diameter is only 0.5mm bigger.

Does anyone else have 1st hand experience from installing the H&R swaybar kit?

Didn't you just answer your own question then? H&R says to just resuse your stock stuff?

So just do that?

And if the H&R bar is only a half a millimeter larger, it begs the question - why did you even bother?

The vendor says to reuse the hardware, not H&R so just wanted to verify if anyone else had the same experience so I can proceed with installation without having to stop along the way because some parts are missing.

Diameter of the bars are not the only measurement to take in to consideration but also material stiffness so thatís the reason for bothering!

I installed the front H&R sway bar on my car. Reused OEM hardware, but also used the supplied rubber bushings specific for H&R application. The rear bar should be the same. Let the vendor know that the bushings are missing.

I'm curious that it is only two mounts on the each sway bar, how did you installed both stock and H&R bushings?

Sorry, what I meant was that I reused OEM bolts and 2 sway bar brackets, but used the 2 H&R supplied bushings instead of the 2 OEM bushings. I only replaced the front sway bar, not the rear.

This make sense . However, is the H&R bushing tight or fit when youíre installing the bushing? Did you have to force pressure by brackets and screws?

It was a very snug fit but nothing too bad. Everything assembled just fine as far as I can remember.

Give us a report on its feel and performance. Iím curious if turn-in improved significantly along with noticeably less body roll. My Dinan front sway improved turn-in 100% and getting on the pedal around a corner no longer kicked out the back in the euro MDM mode.
