For those of you out there with the gsl-se rear end, do you have any tips/photos you care to share of the preferred brake caliper orientation to clear the frame?

Thanks in advance.

The current set-up these days is to align the lever on the caliper to match the ROD from the E brake set-up.

Hi Phil,

Thank you for the reply. Have you had any frame clearance issues, or did you do any clearancing of the frame in advance?

Cheers,
Peter

I bought the car with the axle installed. I have no clearance issues. The rear axle was done by the gentleman in Washington IIRC.

PS My 15x7 +12 rims fit with 205/15 Dunlop tires.

Thanks for the info Phil!

I’m also curious about the orientation. In my setup it looks like my Caliper is going to hit the frame.

It may depend on which caliper rotor set-up. I have the solid disc set-up, the vented disc set-up might be different. IIRC Alvin has the vented disc.

Hi Alvin,

Thanks for the reply. I’ve been through that thread various times, and I recall the first post by Michael being informative, however, it has since been deleted. I reached out to him for some advice, but so far it seems like he has been busy.

Cheers

The preferred location depends on several things, but the picture I linked to above is the best, imho. It is not necessary to clearance the frame. If you are running into frame clearance issues I suspect the axle was narrowed too much.

Appreciated, thank you!!!

Post some pics of your build I'm sure others will chime in

Mine looked that way also. Decided to try it, not a problem. Pat

Yeah I narrowed the sh!t out of mine
I have about 1/2 to 3/4 on each side. But my wheels fit perfectly 205/50-15 in the wheel wells. The rearend is not fully in place yet but I’m getting there.

I had Michael from Spriso narrow my mazda rearend, and the calipers were clocked to use the stock ebrake system with some mods. He narrowed it to 48 inches. I had to notch and box the frame to accommodate the travel of the rearend (and the calipers). I actually had a small dent in the frame caused by the rearend travel. It cut the boot on the ebrake section of the caliper and I had to install a new boot. It also almost compromised the brake line on the passenger side caliper. So cover all of your bases. I contacted Michael and he told me that I needed to modify the frame accordingly. I can post some pics if you want. You also may contact Michael for any advice. I had to cut and weld on the brand new, freshly painted frame and body and rearend. I had to disconnect the brake lines, remove the calipers, wheels. It would have been easier to remove the complete rearend and leaf springs. But I didn't know. It was worth it, though, the car is a beast.
