Hi people I'm Nikki, I'm just popping in to ask a few questions as I'm trying to get some stuff together for Jack (Sleeper) when he gets back He was banging on about a 20mm MGZS ARB? And some other stuff like BLOX LCAs and Energy bushings which are another matter I'll address later. Main question is will a zs180 arb (20mm) fit his MC1? What's needed to get it fitted because I'm getting my brother to do it and the secondary q is what parts fit, EK, EG or EF? Or is it all Proprietary? And yes, A girl who knows about cars!
