Default Need to raise suspension for true duals

I currently have the BMR/Koni setup which I like alot but I need to raise it up a bit to stop scraping my Kooks TD's. I was looking at using BMR shock spacers for the front http://www.bmrsuspension.com/?page=p...&productid=506. But what can I use to get an equal lift from the rear? And has anyone used these spacers before to lift the suspension? I plan on changing to a taller tire as well, putting a 255/40/18 front and 295/35/18 on the rear for about .23" lift.
Lowest point of the exhaust is 2 1/4"

if you wanna get the ace end up...

keep the spring isolators in, and wrap the top of the spring with heater hose...

thats what i had to do after lowering my car and having the rear sit lower than the front

I have the UMI shock spacers - they'll raise the front roughly a half-inch and you can stack them if you want more lift. Takes 15min per side to install

For the rear, you can hose mod the top and bottom of each spring with the isolator for a half-inch or so

I'll try to get some better pics bob when the weather is nicer. I just had it installed last Friday and found a few places I have to pass by often will scrap no matter how I try to get around it. I have the stock isolators in still __Z__ and I'm worried about the rear sitting lower than the front if I do add .5" to the front with a lesser lift in the rear with the heater hose mod. The lowered stance is awesome, but I'd gladly sacrifice a bit of that to keep the Kooks TD's.

Wow, that exhaust sits very low. Can you measure from the ground to the top of each of your fenders for me? The shock spacers up front are used to raise the nose about half an inch without impacting shock travel. As VinR1 said, you can add some ride height with the heater hose mod and still retain the spring isolator. Overall, you should be able to get about a half inch added pretty easily.

who installed the exhaust? There's not much you can do with the header collectors but I'm certain the rest of the system can be pulled up a solid inch if not more...

I had it done at a local shop, I'm going back on Friday to get the SES taken care of and I'll see if I can get the exhaust tucked up more, especially at the rear. I expected the lowest point to be the cats.

Front Driver: 25 13/16
Front Passenger: 25 11/16
Rear Driver: 26 13/16
Rear Passenger: 26 11/16

Car is a bit dirty at the moment...

You need to find a new exhaust guy. When I had duals nothing hung lower than my collectors.

That exhaust should have some wiggle room to draw it back up. I can't imagine Kooks sells its true duals with absolutely no clearance like that.

These are right around where you should be, so those numbers are good. Thank you!

A bit? haha jk You should see my GTO!

I gained about 1/4" after adjusting it. I noticed my scraping is at the bottom of the DSL and the rear exhaust section. I'm probably just going to go with 3/4" spring spacers and another 1/4" from the taller tires and see how it goes with about 3 1/2" of clearance.
