Bumpstops aren't hard, they are soft and about 2 inches tall uncut. Suspension travel is proportional to ride height (it isn't 1 to 1). So, 2 inches of strut travel will gives you a little more than 2 inches of actual travel. So even if the car is sitting on the bumpstops you will still be able to compress the bumpstops by pushing down on the car.

Just because it sits on the bumpstops does not mean the car's entire weight is on the bumpstops. If you took the springs out all of the car's weight would completely squish the bumpstops.

Just like you can lift your car a couple inches by pulling on the fender, that doesn't mean you could do the same if you took the springs out.

No one realizes how extremely close to the bumpstops our cars sit after lowering. You would really be surprised if you take the dust boot off the strut.

The only way to really know is to have before lowering coils were installed ride height, after lowering coils, bushes timed and vehicle aligned ride heights. Then we could compare the current ride height. At Pedders, we measure from the bottom of the wheel rim, up through the wheel center to the painted edge of the fender. This measuring style eliminates the variables of the tire size and inflation.



It appears that is how the OP (Jer4251) measured. With 20" wheels the average OE ride height is 690mm front and 700mm rear. Again Jer4251 seems to have measured correctly. Before I go any further I do have a question for Jer4251. Have you added any weight in your car i.e. big time audio install?

no weight added, it sits empry in my garage, rarely have more than 1/4 tank of gas too. H&R got back to me and said that my car looked correct and my rear ride height was the same as other cars with the same kit. I dont know how an advertised 1.3" drop turns into a 2.3" drop. thats a pretty big difference.

I got the same springs and my car has been slammed in the back since day 1. It looks pretty much like yours. It definetely goes down more than the advertised amount in the rear, and yes my bumpstops are cut 3/4" but the instructions said to cut them 1". The tolerance just isnt there with most springs. I've seen these cars with Eibach Springs installed(advertised 1" frt & rear) and they sit lower than mine in the front and about the same in the rear.

For the record, I belive if I remember correctly when I measured mine it only dropped 1" in the front and almost 2" in the rear

But I'm okay with it untill I get some coilovers hopefully soon.

What are the effects of having the rearend sitting lower than the front? i may end up pulling them out and going a different direction

Your rear camber has to be high and high negative rear camber leads to wear on the inside shoulder. You can address that with Pedders eXtreme range rear camber eccentrics. With those installed you'll be able to get into the OE rear camber range.
