  1. SCCA F-Street Setup. What's Everyone Done so Far?

    It was the OEM "slotting" but with an aftermarket strut. This procedure while gaining static camber, also throws off the KPI by a bunch. The s550's Bimmer type front suspension should be worked on with this in mind. By going to C/C plates, we can move the KPI back to where it belongs and get...
  2. My Complete Suspension Comparisons to date, Springs, shocks, Coilovers ETC. READ

    Like most, I've tried the various damper offerings over the years. For a great intro without the black-magic of adjustment, the Bilstein is hard to beat and they finally have them for the s550 platform. Koni Yellow SAs I'm not a fan. Never could get them dialed in and the ride was harsh to...
  3. SCCA F-Street Setup. What's Everyone Done so Far?

    FWIW, some FS legal struts already have the upper mount slotted. You just can't exceed the adjustment allowance permitted by Ford. On mine, I got a full -2.5* which turned out to be too much given the front suspension design (dual ball joints). I'm moving to STP next season. Can run a tune...
  4. First track day coming up and I need advice.

    Do the autocross on the 19th. That alone will confirm what most are saying here. The car is way more capable than you are now. But learning the car's boundaries takes seat time. Practicing certain techniques on the street will pay dividends on the track and A/X. First, the brake and...
  5. Benefit to autocross to learn car control?

    I've found skid-pads OK for finding limits through feel and sound, not to mention physics. I've seen many guys practicing their drift skills on them. I've never had a problem getting a car side-ways or doing a 360 on A/X courses - long or short. While fun, those antics aren't the fast way...
  6. What are your track/AutoX alignment settings?

    I thought I mentioned MPSS on stock rims above that post. In any event, also stock sta-bars and KWv3 at stock height (F 5/8; R 5/10). Does this make any difference for the analysis? Since mine is a DD like the majority on here, most guys are running something similar. The differences are...
  7. What are your track/AutoX alignment settings?

    As I understand it, we want a certain amount of both static and dynamic camber in order to keep the front tires evenly planted in dive and roll. Some static caster causes dynamic camber changes. When the static setting is added to the dynamic outcome, we may have more or less camber than needed...
  8. What are your track/AutoX alignment settings?

    Update: After a few track days and a lot of autocross, I learned that with the front suspension design (double ball-joint) the car has enough caster. Might check for build variations, but generally it has plenty. As a result, camber gain is pretty good as well so we don't need to run as much...
  9. MP4S or Firehawk Indy 500’s

    I run the MPSS. So far two track days and a bunch of auto cross. I run an aggressive alignment on the car despite being a DD. These are 300TW tires and wear like steel, yet are quiet and ride well. I selected the MPSS because the MPS4s didn't come in the sizes I wanted. Much wider selection...
  10. Bilstein HD6

    FWIW, big fan of the Bils. Used them on both my 86 (both in conventional and C/O) and my 01 Cobra. As with all dampers the spring rate and damper must match. The nice thing about Bilsteins is that they tend to have a pretty broad range. They also seem to do a great job without adjustability...
  11. Camber Adjustment Help

    I have no idea how much a typical alignment costs these days, but a good C/C gauge and toe plates will probably set you back $200. Do a couple of your own alignments, and you've paid for the tools. I currently run -2.1* camber and 1/8" total toe out up front; -2.0* camber and .25" total toe in...
  12. Coilover choice

    Note on the KWv1-3. The damper is a quality product, especially their DAs (v3). However, they use proprietary spring rates (won't reveal). The front spring design is a combo of a standard 2.5" C/O spring at the bottom perch and the stock diameter spring at the top. Thus, no conventional C/O...

  14. Front struts and rear dampers

    I agree with the recommendation to consider high quality dampers. I've run everything from the Saleen sourced Gabrials, the KYBs, Bilsteins and Konis, into the higher end stuff (think KW, Ohlins, JRi, etc.). I would go Bilstein HDs over Koni SA Sports any day. I would stay away from the...
  15. Introduce yourself!!

    Welcome> I've owned a number of Mustangs including Fox and new edge Cobra. My s550 is by far the most sophisticated and powerful of the bunch. Moreover, it out handles and has better ride quality than my Cobra with IRS. However, it is bigger and heavier than the previous models I've owned...
  16. Road Rash

    3M Clear film on mine. Took a major hit from a chunk of rubber at an HPDE a month ago; left a pretty good skid mark but didn't penetrate. Cleaned right up with little effort. Expensive but if I'd needed to fix a paint ding in the hood, might have matched the cost. Beside, these films also...
  17. BASE GT BRAKES SUCK

    Better car control and being smooth. I've run my 86 with 13" 2-piston Cobra brakes without fade (yeah - bit lighter). While I'll agree that the bigger Brembos are impressive, I hardly ever get into them that hard and when I do it's only for an instant. Heat control is the biggest factor...
  18. Possible SCCA run tomorrow. Any tips

    1 - I run 28 cold F/R with MPSS; with the P-Zeros, 30 cold. Need to experiment. 2 - Not necessary for auto-x; generally get into second gear and leave it there. Depending on the course, I may start in second. 3 - Generally, out of the box requires a shift pretty soon, so LL is unnecessary. I...
  19. Autocross Tires

    I don't have dedicated track wheels, so my choice needed to be a compromise for dry/wet traction, road manners (i.e., noise) and longevity. The MPSS is very hard to beat. According to Tire Rack, the MPSS replacement MPS4S, is even better. I've run two track days and on auto-x as well as...
  20. What tires are you running on your Stang

    MPSS 265s and 285s. For a 300 TW tire, these things are more than amazing. I wanted a fairly grippy tire for my on-track and auto-x events, but also a decent road-manners tire. These things are a great compromise if one doesn't have dedicated track tires and needs to DD the car in dry and...
