After much research and consideration, I've decided to stick with the 4 lug set up with my 90 Mustang Gt. I'm just going to be driving the car, and not racing it. However, I was wondering if there was a way to upgrade the calipers with something that I could just put on and it would fit with the same size rotors and setup that I have on already. I've heard the SVO calipers, but it seems they are only 1 piston... does anybody have any suggestions?

 

They are one piston, but they go from your 60mm to a 73mm. Sometimes having 2 pistons isn't an "upgrade". I run the svo calipers and they made a nice difference, but you may consider a master cylinder upgrade while at it. They will apply more force, but require more fluid to move the same distance as a smaller piston. In other words, if you run them with the stock mc you may notice a much softer pedal. I run an svo mc but I also have rear disc which is what its designed for as well

 

i suggest an SN-95 5 lug conversion and 99+ GT calipers.... but that's just me.

 

Will the SVO calipers fit my current rotors and are they 4 lug? Is there any other conversions that I would have to do?

 

They will bolt strait up, but I will say on my car I couldn't get the banjo bolts in if the calipers were already bolted in place, they would interfere with the shocks. Other than that get some good pads for the svo calipers and toss them on.

 

The SVO rotors have 5 lugs, but my current set up has 4 lugs. Will the SVO calipers match with the 4 lug rotors that I have already, or do I have to do a 5 lug conversion kit to match the SVO calipers with the 5 lug SVO rotors?

 

My car is 4 lug with svo calipers, yes they do work.
