The Skinny on H&R's sportcoilover ride height

In another thread from a far distant galaxy...we were discussing H&R ride height. Apparently, and many phone calls later, H&R offer a number of different springs lengths for the Sport coilover kit. If you do not like the height of the 'stock' kit, you can order a spring that is identical in rate but 1,2,3...inches longer. I was informed that other spring rates are available too, but I ran out of energy before confirming this.

H&R are out of stock and there is no ETA. I was told to call back in four weeks. I have no part numbers to share at this time.

As I wrote in my other thread, the ride height is a tad too low for me - another 1/4" would be great! The difficulty here is that the front spring is a true progressive rate spring. So as we raise ride height, the spring is compressed fairly far into its progressive range.

You cannot order the kit with different springs - it comes with one spring length and one spring length only. The additional springs are about $70.00 each +/-. you can order the springs from whom ever your kit was ordered.

Another 1/4" in ride height and two more inches of spring travel This in no way should be taken as knocking H&R. Plenty of folks love the ride height and some like it lower . But H&R realize that a few Mini folks have complained and they have responded for us few Even with the cost of the extra springs, this kit is very nice! Zero regrets.

that may be a good option... good to know. I may try that too...

maybe a question for the experts; swapping in a longer spring (or a stiffer rate) will raise ride height... but, wont this also make the wheel/tire/suspension unload too readily, i.e.; riding around with the damper closer to full extension???

Within reason, no. The spring should be an inch or two longer at the same ride height. If a spring is compressed too far it will reach block height and bind. Think of the damper's stroke and then imagine moving a spring up and down the damper's stroke. Where the spring sits ultimately determine where its optimum range is too...but the difficulty here is that a progressive rate spring acts progressively when being compressed to achieve ride height. Whereas a linear spring doesn't care about anything but block height - affected by rate and length. Once the progressive range is used up, a progressive rate spring becomes linear...but there are lots of spring types out there.

H&R will have this figured out for sure! You can comfortably go with a spring two inches longer.
