      For example I've done several DC ProSolo (Pros are drag starts with Christmas tree and two cars going at it on identical mirror courses), the surface of that venue is nothing but uphill/downhill with constant elevation changes. Without a handbrake start once staged, you're either rolling into the light for a DQ or rolling backwards (depending on the event course orientation). It's not like drag racing where starts are usually flat, Solo brings other elements into the mix and that's why it the sport of all-around cars and drivers.
      I've been on unlevel drag strips before, and had to do the same. Yes, it's a PITA. You just made it sound like you aren't using the AEM's launch control capabilities in your previous post. I just know you have real rubber, and didn't know if there was more of a reason to not truly launch drag style. Obviously course layout and the distance to the first turn comes into play too!

      You're absolutely right, it is a real PITA when you have to worry about the Christmas tree and reaction time (if slow, reaction really kills you since the clock starts rolling with the green), then to have a rolling car adding to the difficulty of the launch is an extra unwanted layer to the routine.

      Below is what I did to the handbrake to help these situations. The trick had served me well and all you need to do is pull it - preload the clutch while sitting on the 2-step - then let it go when needed (the hanbrake self-locking ability is still functional on the last two upper teeth). Call it poorman stage brake:

      Do you think that would help or hurt driveline shock to the rear on an aggressive drag launch since it's disabling Haldex via the handbrake switch as opposed to having the F/R locked 50/50 via an aftermarket controller? I know next to nothing about AWD launching, but that'll have to change soon!

      I can't remember Max. You running SP or Street Mod? Was just browsing the 2015 SCCA Solo Rules last night, and apparently SP rules require that the vehicle has an operating hand brake ( or foot brake ). So good thing that you kept it. SCCA sure has some strange rules....
      "...I recommend books. People who don't know what they're talking about are less likely to write a book about the subject...."

      I don't think it makes a difference. The rear engagement is only happening when the ABS sees front spin, and that's regardless of emergency brake signal. Therefore, that kinda negates the drawbacks that you're thinking about. Rear engagement also happens in a fraction of a full front rotation, so pretty quick where the handbrake technique is not really affecting the 4-wheel performance of the launch. Not sure if what I wrote made sense ...

      Richard, I have moved to Prepared now (F-prepared specifically since the car is also have XP eligibility). You're definitely right about strange and often ambiguous rules with SCCA Solo - another reason that pushed me to Prepared where there is much more wiggle room for a builder type of guy/car.

      Has anyone else reduced weight of his tt? I am looking to reduce mine's because 1400 kg seems to be still very heavy although i have already remove all a/c accessories and the heavy metal inside the back bumper. My tt is roadster BT.

      Hi, I have a 225 roadster and have done a fair bit of weight reduction. I'll just quote a post I made on another European forum, that way you can see the weight in Kg.

      - Lower dash panel 6 lbs /2.7kg
      - Misc plastc interior pieces 20 lbs/ 9.7kg
      - Carpet 25 lbs/ 11.3kg
      - Convertible top 85 lbs/ 38.5kg

      I wonder if the RB kit for the R32 would fit the TT (massive weight savings over the stock r32 brakes)

      You probably could make it work with some tweaking (new carriers and possibly lines). If you're seriously in the business of weight saving, there are even lighter kits available for the TT though. Willwood makes a kit that is super light (caliper and rotor together), but retains similar mechanical leverage as the OEM TT setup.

      Good to know Max. Any word on the kit's actual weight savings compared to stock?
      May consider if significantly lighter than Boxster option (which it may be as Boxster brakes use OEM rotors)
