Welcome To British Carbon Tuner Racing. This tuning co. tunes up the less common cars such as the ZZ-S and Lavioette. The aim is not only to provide a car that is quick, but a car that has perfectly balanced handling.

I tested both the stock and modified car at the High Speed Ring. 15 laps in each.
The stock car pulled out a 1:18.999 which isn't too bad. The modified car thrashed the stock. I managed to pull out a 1:08.071. Thats 10.828 seconds quicker.

ONE WORD OF CAUTION: The Spirra II tends to oversteer very badly at high speeds. When it gets to about 150mph, the car becomes very twitchy so very delicate steering is needed. It can be countered by using R1 tyres.

I will happily accept any suggestions for improving the performance of the car, and I may tune up a few more if anyone shows some interest.

Welcome to our humble forum badass.

Yea, I know all about the Spirra oversteer characteristics. 👍 I don't have time to drive your car today but the settings look like they make sense.

It doesn't get much sweeter than this. Prepare to drive a car with ultra smooth handling.

TESTED AT: SEATTLE
I chose a track that has some nasty corners and Seattle fitted the bill perfectly. This time, I did 5 laps with both stock and modified and BOB did 5 laps on "Increased pace (4)"

LAP TIMES

Greaterbadass BOB
stock 1:54.379 1:56.062
modified 1:37.000 1:40.083
difference -17.379 -15.979

I mean 17 seconds is a big difference. I only expected about 5 seconds but 17 The ZZ IV is guaranteed to wipe the floor with the Japanese Compact Cup (even though you must use sports tyres). Enjoy! 👍

"Wipe the floor with the Japanese Compact Cup"? Meh, I like easy races, but don't make them too easy!
