Oem 19's With H&R Wheel Spacers

I have the oem 19's and H&R springs. I want to get wheel spacers for the front and rear to make them more aggressive and stick out a bit without rubbing.

Anyone have this setup?

TIA
Kevin

It will work just fine with 10mm spacers all round

FYI: this would have some negative impact on the scrub radius of the front suspension.

this guy has H&R's with OEM 18's and 10mm spacers. I would think that this setup would work with the 19's as well.

Good luck.

How have the H&R's affected performance/ride?...

I ordered mine, there suppose to be here next Friday, you guys think the front wheels might rub with the car????? I don't think there's a negative effect, it's only 2cm wider

More details, por favor.

Wouldn't be a large nor really noticeable effect would it?

Not likely with just 10mm and the amount of steering boost we have.

Basically by moving the wheel away from the pivit point for the steering the tires get more leverage on the steering any tims the wheels have a forward or backward thrust. Best example would be hitting the brakes. So what will happen is there will be more kickback in the steering on uneven pavement.

Another side effect is you reduce your effective sping rates by providing a larger lever arm reducing the motion ration of the suspension. You basically are using a longer lever to compress the cars springs.

At 10mm the delta should not be an issue.

The most common problem with spacers for this usage (just moving the wheel centerline away from the stock design) is the extra load and wear it puts on the wheel bearings.

I agree with all of your points, I am running 10mm spacers all round and prefer the feel the steering it has a little more feel and weight as a result of the contact patch moving 10mm further out.

I ran 10mm front spacers on an E39M5 and it had a similar beneficial feel, I did 70k miles with this set up and the wheel bearings were fine. The delta on leverage an hence the slight reduction in wheel rate will also be very small. It also reduced understeer magrinally.

I am currently running 12mm rear spacers as there is room and I had a set spare set from an E46M3 (again I used them on the fronts) and it feels slightly worse and less balance than with 10mm all round.

I have spoken to very knowledgeable suspension guru's and they tell me that I should not be able to feel 4mm of additional track on a race car, let alone a road car. I will swap back to see if I am paranoid !

All in all 10mm all round appears to be an improvement to me anyway.
