    how to do a compression test?

    Does anyone have any specific instructions on how to perform a compression test? What fuses need to be pulled? How do I disconnect the fuel pump? And how do I actually turn the motor over with the auto-starter? Thanks for the help.

    Stock power/suspension, M6, what breaks first?

    As the title asks, with a stock suspension car at stock power levels, what breaks first at the track? My drag radials are worn out, and I need to replace them. My car is now my daily driver (used to be weekend-only), and my doesn't want me to get new rubber for the strip for fear of breaking...

    Sportlines vs h&r SS vs ??? - spring rates?

    I want some seriously low springs, something like the sportlines or the h&r SS springs. I believe both sets are progressively rated. Which spring has the higher overall spring rate? I want a higher spring rate - I believe stock the brembo cars are very under-sprung. Or is there a third...

    Reuse OE shock dust sleeves (rear)

    Has anybody ever attempted to reuse the dust sleeves from the stock rear shocks? Can they be removed without much difficulty? Just want to make sure I'm not biting off something inadvisable, such as reusing the stock strut mounts.

    Disappointed: better air = slower mph?

    A few months ago, my car was running 113mph on street tires and 114mph on DR's. That was at ~1700 DA if I recall. Yesterday, at the same track, I drove the car to 112 and 113mph, respectively, in ~350 feet DA. I have made no changes to the car, except for one. Just before Christmas, I...

    LCA bushing maintenance?

    I know it really depends on the type and material of the bushing, but what kind of maintenance is required for LCA bushings? I live in Alabama, which is a humid state with practically no snow salts. And I only put maybe 10k miles a year on the car. What is involved in maintaining...

    Alternatives for 15x8 wheels?

    Are there any cheapish alternatives for 15x8 wheels? I don't want to spend a fortune on welds or racestars. I want to mount up some 275/50's to them solely for track duty. Just like my current 16, I would only mount/unmount them at the track. And I'm only going to be pushing down stockish power...

    Love this car: [email protected]

    My car is a 2011 M6 premium+brembo with 3.31's. Back in the spring I ran a 12.17, but the traps weren't working. That was in pretty good air, and the car was still bone stock on some DR's. Yesterday I ran a [email protected]. The air was worse at about 1900 DA, but not awful. Since the spring...

    Opinions on roush mufflers+resonator delete?

    I currently have the roush mufflers, with everything else being stock(manifolds, cats and h-pipe). I have scheduled an appointment to have my resonators cut out. I really wanted to get the jpc over-axle pipes, but my wife would not allow me to spend the money :mj:. Anyway, I've seen a few...

    Custom Exhaust Tips

    Has anybody modified any of the mufflers/axle-backs with custom exhaust tips? I know this is silly, but for years I had a g35 sedan and suffered from coupe envy. I was particularly jealous of the looks of the various aftermarket exhausts available for the coupe. Even today, all of my friends...

    Cost-effective NA power

    I've decided that I'm not going to chase every last bit of power with this car. Instead, I'm going to settle for middle of the road numbers, on the motor. So on that theme, what is the best application of $$$ for power? Off the top of my head, I figure the best would be a tune, followed by...

    Colored headlight/fog tint?

    I've been playing around with the idea of doing tint/overlays for my headlights and fogs. My car is a Kona, and I think yellow would go well with the blue. I've been considering this idea for a long time, especially after seeing the pictures of Vorshlag's shop mustang. It would be a cheap way to...

    Old DR's doing work

    Went to the track this past Friday, and although I could not beat my previous best, I did cut a few good times. The best part of the night was cutting a 1.71 sixty on one pass. I know that's not particularly amazing for most folks, but I was impressed. The only modification to the car is...

    Anyone ever tried exhaust silencer inserts?

    After over a year of being stock, I finally put on my first mod last Friday: the roush mufflers. I really like the sound of them, but I want them to be even *louder*. Yeah. I'm considering removing the cats at some point in the future, but I've read multiple accounts of roush mufflers+cat...

    Replacement DR's for 255/50/16

    First question - how can you tell when DR's have reached the end of their lives? I've got a 5 year old set of BFG's that are all but slicks at the moment, with probably 150 passes on them. I can still launch on them a helluva lot harder than I can on my brembo tires, but I'm wondering if new...

    New member: 12.173 stock + DR's

    Short:I ran a 12.137. Long: First post here, but I've been a longtime lurker. I finally decided to join so that I could share my 1/4 time. Yesterday I went to Steele (Alabama) and ran a best of 12.173 with a 1.807 sixty foot. Sorry, no trap speed. This was the first weekend the track was...
