Teesside Autodrome - Evening Trackday 25-04-2022
Arrived early at 4pm to secure a spot in the pit lane with my m8 Dave in his blue civic
swapped over to the 595RSR semislick track wheels. wasn't sure where to start with these new BC BR coilovers, so I began at their hardest setting 30/30 clicks.
Car setup / changes
My last trackday was in 2020 with Jamie (LetsTorqueCars). since then, kassandra has been fitted with:
- BC BR coilovers with softer 4/3kg springs,
- Cold air ducting,
- Fresh GTIR oem front brakes
- Rigid bucket seat frame
- New seat belts
- New PAS pump
- Fresh CG13 gearbox, Open-diff
- 2.5deg front camber
- 0deg toe

I noticed the track was quite bumpy with lots more patchy tarmac repairs. The tyres are also barely warmed up after those gentle 3 laps, also found my rear left tyre was almost flat so I pumped that back up

The 8yr old rear tyres are really showing their hard age being really slippery when cold compared to the 6yr old fronts.
They take at least 3-4 laps to heat them up, clean the surface and reduce their oversteer.
With front & rear dampers at full hard & rear swaybar at full hard, the rear end is very light & sensitive to lift off oversteer.
Also noticed the 3yr old wideband sensor was showing E8 error during cooldown, heating element might be struggling with the intense temp difference & might need replacing someday?

Brought Dave along for a ride to see if the passenger weight helps balance the car, but with all dampers at full hard it's still very sensitive to lift off oversteer. a slight amount of oversteer might've helped turn the car mid-corner so I could accelerate earlier down the straights but overall it still loses time.

@10.40 180 bend entry oversteer
Now that the tyre pressure & temp has stabilised and after softening the front end to 15 clicks & rear to 30 clicks, she's slightly more balanced through mid-corners. Rear end is more stable when driven smoothly. The fresh GTIR brakes bite really well when warmed up after 4 laps.

Next I went for a ride in Daves civic. It's alot comfier & quieter than mine although the standard seats don't offer much support as I roll around lol. it was a few nice laps till we went past the 1st bumpy hairpin and then it suddenly lost drive ?
hazards on, we got tow'd back to pits to assess the damage
turned out the driveshaft had snapped off the CV joint where the spline is, seems to be a common honda issue I heard ?
he awaits the recovery truck home

Whilst dave awaits his recovery, I went for a last run with the dampers now set, slightly less fuel weight and no passengers.
Tyres are now stone cold so the out-lap will be tricky on these old tyres

Once again the old rear tyres were very slippery when stone cold. The balance stabilises after a few laps & tyres heated back up.
Assessing & comparing my laps to the previous trackday, it felt quite good near the end.
My fastest lap of 57.32sec is approx 0.20s faster, mostly due to improved acceleration from the cold air intake ducting in the wing panel and can brake much later with the fresh front brakes.
