I wonder if something else is wrong. Perhaps in the MC restricting the rear line pressure. You have a LOT of rear bias, no reason the fronts should be locking up first.

Yes i installed custom hoses. I will give you a list of the part numbers i used when I can look them up. I will also snap a few pics this weekend.
Edit: Here are the part numbers:
These go in each caliper

These go on the hardline on the car

These are the hoses I used
http://www.summitracing.com/parts/EAR-63010116ERL/
I chose hoses with straight fittings because I wasnt sure how close to the wheel the hose would get with 90 or 45 degree. You can try a different end. I route the hose in between the trailing arms, up to the fitting on the car.
All the fittings and hoses for all four corners cost less than a pre-made "kit" for a C4, and I can change hose length easily if I change brake setups in the future.

you know what my friend, i was thinking the same thing too, actually since i have stock c5 up front, and bigger rotors and the c5 brakes on the rear + DRM bias, i should be locking my rear first!! i was thinking on the first days that the pads needs to set first, but now it's been more than a week, i tried them this morning in a parking lot and felt the front locking first, the pressure on the rear felt good when i was bleeding them, i dont know i may need to bleed them again.... by the way do i need to bleed all 4 wheels? i only messed with the rear, and what is the best way to bleed the abs?

Even if the pads were not properly bedded the rear should still lock firstI would think.

In my 93 there is a line from the master cylinder to the ABS unit behind the drivers seat. The ABS unit has a bleeder valve on it's side. I used a Mity-Vac pump to bleed that line out.

i know i looked everywhere but i couldn't find a bleeder on the abs unit so i ended bleeding through the lines where they conect to it one by one, when i change the rear ss brake lines to a longer ones i will take a closer look to see if i missed it....

I don't think so, I've bleeded too many cars before, but normally when there is air in the system u can tell by stepping on the brakes twice and if the second step felt higher it will mean it needs more bleeding but mine feels really good now and doesn't do that , but anyways when I change the ss brake lines I will bleed them again
