Which have a higher spring rate??

I'm choosing between

H&R sport
spring rates???


and

Eibach Pro-kit
Front: 148 lb/in
Rear: 456 lb/in

I dont know the spring rates on the H&R's, I don't want to suffer over bumps so this is important to me.

also, since the H&R's drop a bit lower, I'd images the shock (im using stock sport pack) would have less room to compress over big bumps yielding a more feedback to the driver.

Thanks for your input!

if you do a search you'll see that 90% of the reviews/responses show the eibachs to be more comfortable than H&R. However the reason why the H&Rs are less comfortable could be attributed to the fact that they sit lower than eibachs and therefore have a tendancy to ride on the bumpstops more often.

Now are the H&Rs on it's own comfortable enough? This can only be answered by you cuz it varies ppl to ppl. However just switching to non-runflats will make a world of difference as far comfort is concerned.

Thanks, I had a general understanding that the H&R's were stiffer then the eibach's, my question is what are the springs rates! im seeing that nobody has this info.

Ive decided to go for eibachs anyway for the way the 'i' drops on an 'xi'

thanks for your input
