Yes, even stripped, my old MK5 was a lard arse - but it was softly sprung & stiffly damped and would run rings around most stuff on track, particularly in the wet. It practically telegraphed its intentions too, lift-off oversteer was something you could use, rather than try and avoid. I hate snappy cars.
Ohlins aren't some fly-by-night outfit, I'd trust their judgement implicitly and set the car up around the kit to compliment it.
