Koni # 70.34.53.000.0 is what I'm looking at. 16-20mm Rod Dia.; 55mm Length; Progressive Soft.
I'm on modified stock springs and ride height is at 26.5" front, 26.75" rear. Using Bilstein shocks and struts. I want to modify or replace the bumpstops all around to regain some suspension travel and control (will already be modifying the upper mount in the front to get that extra travel).
If I used the Koni bumpstops all around (replace front, ditch factory rears and mount the Koni bumps on the Bilstein shocks) would that work?
If I used the Konis up front and trimmed the stock rear bumpstops half an inch (and reshaped to keep the taper) would that be a better option than going shaft-mounted bumpstop in the rear?
Or is the 55mm too long for the front and/or rear, and would the 40mm Koni be a better option for either?
I've searched and searched and searched, and even PMed JasonWW, but I'm not getting any answers. The last thing I want to do is start changing stuff out and hammer the hell out of the shocks by bottoming them out, but I do want to maximize my travel and control, and replacing the stock stops seems like the best option from what I can tell.

Thanks for the PM and the advice 99. Very much appreciated.
How do you feel about the rear BS? Keep the stocker, cut it down, and reshape it? Or convert over to the 55mm Koni shaft mount BS? Obviously ride is important here, but at the same time I don't want to compromise the shock.

I think trackbird from this site and frrax had tried this before on the rear shocks and bottomed out and broke his shocks. Not sure what exact combo of everything he had... I'd do a search on it.
