Just swapped out my H&R Sport rear springs on Koni for the HP Swift Conversion!

stashtrey · 10-03-2013, 12:13 AM

No more rake/dump in the rear. Will post pics tomorrow. Definitely a good investment I'd you are not happy with your H&R sport height.

Swift 60mm 9" 570 lb spring, thrust sheets, thrust bearings. Easy swap. Have the collars flush with the end of the perch and so far its perfect.

Highly recommend. Next up is the front coilover conversion!

stashtrey · 10-03-2013, 11:16 AM

ajsalida · 10-03-2013, 01:30 PM

Rear Konis are same as non xi.

stashtrey · 10-03-2013, 01:54 PM

Good to know.

Been driving on them today and they feel great. No major differences. The swift springs are a great upgrade!

Yes, that is correct.

i and xi share the rear suspension.

Will post pics of springs and before/after as well as how I installed them. Was not as tough as I thought.

Are you noticing a difference in ride quality?

Honestly... no... it's almost seamless. It feels tight and comfortable. Nothing noticeable at all. Highly recommend.

Do the Swift springs split the difference between stock and H&R sport springs as far as drop goes?

stashtrey · 10-04-2013, 09:12 PM

You can go stock ride heigh and all the way to full dump. I'm sitting perfect in rear now and was able to raise up close to .75" from the H&R easily. Plenty of rom if you use the HP Adjustable ride height adjuster perches. Higky recommend the thrust sheets and thrust bearings. They add height and also slow the sprng to rotate and easy adjustment.

Will post before and after pics later. Wish this site would allow bigger image files. My pics are too big. Need to resize them.

I am 110% satisfied and will be doimg the front conversion on my konis with the swift coilover conversion.
