I don't own a SV but have worked on a few. I think they have always offered a roller. The rear drum brakes are probably standard for a lot of Cobra. Rear disc would be an upgrade. It depends on how your going to drive it, street or racing whether you "need" rear disc. Remember the drums where made for 3500 to 4000 lb car and your Cobra should be less than 2600 lbs. I think the choice of tires are more importance.
I was researching Cobra in 98, 99 and 2000. I did look at the SV but I do not remember their price. I would think $9,000 to $13,000. But the price in 2001 has little to do with today's price. Today is the day of bargains in the Cobra world.

Maybe others will post their opinions.

Welcome to the Cobra Family. If I had known about Club Cobra in 2000 I could have save thousands of dollars and hundreds of hours on my build.
