I'm sure we'll have pads by summer, with the Fiesta ST winning all these awards and stuff, they gotta be making pads, hah.
What was the curb weight of your SVT Focus? I'm kinda thinking XP10 might be overkill with this car, you may even be able to get away with the AX6... possibly.
There was a long-time focaljet.com guy that did a comparison of the SVT Focus and Fiesta ST. He listed these comparative stock weights:
* SVT Focus (not sure if that is 4-door or 2-door): 2750
* Fiesta ST: 2742
Can't get much closer than that.
My SVT Focus had a 6-point cage and was partially gutted (stock seats removed). I reckon the cage added close to 100 lbs (not the ultralight tubing) with the X-bar at the door, etc. minus maybe 60 lbs for the stock interior. Add racing seats back in, take out the airbags and stock wheel, and it gets to be a wash. I figure when it was all done, something around 2800 lbs is about the number.
But the main weight thing is the driver, unless you are Danica Patrick-sized. I'm not giant, but still have a significant weight effect.
I might try XP8s in the front and AX6s in back (assuming they become available)...or stock pads in back. With these FWD cars, it's all about what the front brakes can take. The SVT brakes did amazingly well with XP10 (I think I also used XP8s, which were fine as well). Very progressive (although the initial bite was sometimes not what you'd expect) and practically no fade over the course of typical 20-30 minute session. Legit brake fluid makes a huge difference. I also had Goodridge braided teflon brake lines, which worked great for the 8 years I tracked he car. Having said that, I also had Porsche cooling fins installed which made a big difference. I plan to do that with the Fiesta ST. I was surprised to see that the Fiesta brakes were smaller than the SVT brakes. That's a little bit of a worry, but I think better pads, a cooling strategy, and proper fluids should do the trick for recreational lapping.
