At any rate, in my car the acceleration available in fifth is so marginal it is not needed on the track. For example, I kept the car in fourth down the Ullman straight at Sebring, which is a fast entry 0.6 mile long straight terminated by a high speed right turn.
In terms of stability of the chassis, spreeds over 100 mph have not been an issue. I prefer using the stock tire size. Suspension on my car is essentially stock configuration with new components sourced from Spyder. Stock configuration brakes and steering are completely adequate for elevated speed.
Don?t know about others, but I get a hell of a lot of body lean in slower speed corners. Installed new shock cartridges and rubber springs for next year, so will se how that all works.
For next year I have installed a very cool engine upgrade which should give me a lot more power. Will be interesting to see the improved top end.
What the five speed and taller diff offers is more relaxed cruising. This is really great over here as we travel such long distances to various events. e.g. my home track is three hours away and I have taken several multi-day trips in the Plus 2.
What combination of Gearbox, diff, and tires do you have now?
Cheers!

I have a 1700cc BDA fitted that has a dyno sheet showing 166 at 7000rpm. It's in a mild state of tune with twin 40dcoes
