  1. If your rev limiter is set to 6400 then your current top speed is 150 if u can hit the limiter.

    With a 3.68 it will be 138, a 3.94 would give 129mph.

    A good change to make is add a 3.94 diff but also a 0.76 5th gear, this will give the acceleration improvements your looking for but also decent cruising revs ant top speed (142).

    Id only go for the 3.94 if you have an early vr or a remap for the 7000rpm rev limit though, I plan on getting the 3.94 diff and 0.76 5th if I keep my car much longer.

  2. Toe in on the front wheels greatly improves turn in and gives more grip in the corner' date=' it does make the steering at higher speeds very twitchy though and will increase tyre wear.

    Apparently in a fwd car it will also give more grip on standing starts as the wheels will be pulling forward and flexing the bushes so they will both be pointing closer to straight ahead wheras with neutral toe on a standing start the wheels will have a tendency to toe in.

    u mean toe out??

    Yip. !shy

  4. The schrick is actually an advantage on track, especially when combined with an atb diff.

    Ive found in the past without the schrick that certain 2nd gear corners the revs would drop a bit low and the car would bog down, and theres no way I would have went for 1st. Also, some longer 2nd gear corners ive sometimes found the engine bouncing off the rev limiter before the exit wheras with the schrick its fine leaving it in 3rd giving a higher exit speed.

  5. That used to be the case but most modern rolling roads use more complex calculations and partly measure the drivetrain losses with the coastdown method to give an accurate, repeatable flywheel figure.

    If you look at wheel figures only you wouldnt know if the mods had made any difference as theres a lot more variables including air temp, gear oil temp and so on.

  6. Started with Toyo Proxes T1-S, 2 sets. Very grippy and predictable tyre wet and dry, but a bit soft for my liking, could feel them squidging about and they wore down quickly.

    Moved onto Fulda Carat Extremos, not too different in grip levels from the Toyos, but not as soft. Wore well driven normally but hard cornering tore them apart.

    Now got Bridgestone RE 720's and am well impressed. They grip better than both the above and wear extremely well. Done 3 trackdays on a set now and they look almost new at the back and only a bit worn at the front. A bit less predictable than the Toyos but there a very good tyre and id get them again.
