If you lower the perch at all in the rear you will actually take tire clearance away, not increase it. I really like the way you did it for the rears as long as you do not lower the perch at all. I would mark the top of you sleeve on the strut and make sure it's at that height when you are done. Personally, I don't mess with the back of the b13 perch for that very reason. Just a warning for those that didn't know that part.
At worst the GC perch can't go much lower than it would be able to if the OEM spring perch were still attached right? It looks like you could just lower the GC perch as low as it can go with the OEM perch still attached, measure and mark the position and use that as a benchmark to not go any lower. I THINK that is what Steve is talking about. I don't think it should be an issue as long as you don't take the GC perch below where it could have gone if the OEM perch were still attached.

No cutting perchs helps you get a perfect flat base for the rear perch to sit on. If the strut you are using already has that (some do) then cutting perch's is cosmetic really, nothing more in the rear. In the front especially on a B15 you can cut the perch, lower it by bending the tabs out at a 90 and get a longer spring on the front. B15's are cursed with limited room for anything longer then 6 inch's otherwise. 7 is possible with a cut perch as I described above.

Steve, can you explain more how moving the sleeves down in the rear would make you lose tire clearance? The sleeve sticks out no further than the stock spring perch, we know this. If we are worried about the lower spring perch on the GCs being too low, they are GCs, you have more than enough room to adjust them to the same height had you not lowered the sleeve mount (original spring perch).

HOpe that came out right.

Simply take a look at the B13 rear from the rear looking forward. The tire is right next to the oem perch. GC sleeve sits on the perch and slightly above the tire. Almost zero room with a 205 because it hits the perch or the tire (can't remember which first). If you cut the perch and move the sleeve down have just made the tube 50% thicker in diameter, now the GC sleeve is going to hit the tire if you go too low.

Sadly I don't have a B13 to look at... being that I am about 1000 miles away from mine... So let me try to understand this.

If I am understanding you correctly, the OEM perch sits above the outside brim of the tire. Something like this:


Code:
      |/|
      |/|
     _____
 ---  | |
|   | | |
|   ||| |
|   |||_|
|   | 
 ---
and by lowering the perch for the sleevewe run into this problem

Code:
      |/|
      |/|
      |/|
 ---X_____
|   | | |
|   ||| |
|   |||_|
|   |

thats whats he's saying... sorta if I understand.. I always had a problem with aftermarket wheels rubbing the strut not the perch in the back of my B13's so if you lower the sleeve it makes the tube of the strut fatter and hence wide 7" wheels will rub the sleeve unless you have a crazy offset or spacers. it's funny I have some older BBS moda's that are 17x8 and they fit without spacers.. I don't know the offset but it's nice. the 205 are really spread out.

Screw ASCII, how about some pics?

- driver's side

- passenger side

No more than a business card would fit between the strut and the tire. 205/50's would be rubbing without any doubt.
Driver's side with 5mm spacer

Passenger side with 5mm spacer
From this thread: Link

Offset will play a part in rubbing the strut and also the location of the GC sleeve - how far you lower it.

Holy crap that's close. That is mostly due to the offset of the wheels though, correct? The rubbing issue with the GC setup would occur if the coilover PERCH were lowered past the top of tires but it would be impossible to drop the SLEEVE past the OEM perch welds. Going by those pics it looks like the GC sleeves should have no problem clearing the tire with an OEM or lower offset, unless I am grossly underestimating the outer diameter of a GC coilover sleeve. On a side note, does anybody know the inner and outer diameter of the GC sleeve, specifically the B13?

Hey i was looking at the cutting you did on the AGX's and im getting ready to do exactly what you did, however i was wondering if the two tabs you left on the rear struts where the lower perches were, are strong enough to hold the weight. i just dont want the two tabs that i leave on to snap when the weight of the car is on them.

thanks alot.
steve.

If you look closely at your lower spring perches you will notice that there are only two places where it is welded to the strut housing. When I chopped it up, I left those two welds untouched. Those welds dictated where the tabs would be made, and how wide I would leave them. As such there should be no difference in strength!

They are over 3 inch OD. Tube is under 2 inch OD. It depends on the shape of the tire as well. A tire that gently rolls from the shoulder to the tread has more room for the perch. A square edge tire has less. You now see the amount of room for error you have. That is why I recommend leaving the rears alone and just using the oem perch.
