i normally run 16's, once i had put on some 18's which had good tread to go down to meremere
i was off my pb by 0.1s, but throughout the day, on average i was running roughly the same times.
could definitely feel the car being weighed down coming off the line, but fortunately boost+awd negated that somewhat
low speeds and off-boost is where its really felt, once the wheels are spun up its not so bad
