I just changed 225/40r18 eagle GT Square settup. And felt some difference. I felt it harder to kick my rear out, which was wat i loved to do.

So I was thinking to get RSR coilovers to drop the car around 25mm front and rear, and make it full soft front and stiffer rear. use LCA and camber bolt to set around -2 front and -1.5 rear camber.

Would u plz tell me that whether the full soft setting is much stiffer than regular lowering spring or stock? its my DD car so just dont want it too stiff.

@Moto-P And will I feel better with these coilovers? I know stiffer suspension may make these new tires less gripy and offer me a feeling like factory setting or even easier to kick my rear out.

Thanks!!

@Moto-P Funny you mentioned about the top mounts being 'reversible' to get more camber - my mechanic mentioned that to me after he'd finished installing them but I didn't think it was 'designed in' at the time.

6 month+ review:

Been out on track a couple of times now, done a couple of AutoX events, done some serious canyon carving and even a bit of drifting. Whole lot of daily driving too.

Couldn't fault the car out on track. Still running the 'out of the box' Moto-P setup, the alignment I post earlier and street tires. It's not the fastest or edgiest thing I've driven but it was still surprisingly, pleasingly competent out there. Tons of grip, very neutral, very well poised over bumps and kerbing, very confidence inspiring when pushing really hard with the DSC completely off. I found that the car was also very progressive at the limits which meant that I could just dive in and enjoy the drive instead of having to worry about the car biting me or having to drive around any pronounced chassis imbalances towards either over or understeer.

When AutoXing I did encounter slight signs of understeer on very tight, brake-hard-heel-toe-REV-and-grab-first type Autocross/gymkhana obstacles but I'm hoping that some simple rubber and alignment tweaks might fix that. Or it might just be me overdriving the car like a hack, the course surface being a bit dusty etc. Minor detail.

As far as lightly competitive or very high performance use goes I'm certain that there's faster setups to be had with more extreme rubber, more aggressive/higher end coilovers, other chassis mods and a more diligent attitude to small setup tweaks (tire pressures and the like). I honestly don't feel like I'm leaving too much on the table in terms of raw capability though, even if I might well indeed be giving up a tenth of a second here or there versus a truly hard core setup. I guess we'll cross that bridge whenever somebody local shows up with another prepped ZN6 and starts turning up the heat.

Meanwhile out on the streets the car passes the 'girlfriend test' with flying colours. I don't think she's aware that the car has been modified at all. The passenger side visor always seems to be down when she's in the car because she's fond of randomly (and barely noticeably) touching up her makeup on the go. Most importantly to me, my passenger seems to feel every bit as comfortable riding shotgun as I do in the driver's seat even when I'm driving rather quickly or on rather curvy roads, or both.

What next? I might play with camber and slightly grippier street rubber from here but that's about it. It's extremely refreshing to be able to just drive to the track, bang out some runs and drive home again drama-free without feeling like I'm leaving much on the table. No hassles with changing to R-comps, fiddling with multiple suspension knobs and constantly fretting about tire pressures.

If there's one crappy attribute of this car it HAS to be the brakes in my opinion. The stock setup simply doesn't handle hard use very well and the braking deficiency suddenly becomes quite a glaring sore spot once you upgrade the rest of the chassis. Fluid/lines/pads bring things up to scratch very nicely indeed but I opted for a 4 corner Alcon BBK so I'll simply never have to think about fade again, ever.

I'm pretty broke post-BBK at the moment but at least the car's set up like a treat. Full warranty on the engine intact, breeze to daily drive and it's ready to throw down and dance hard, any where, any time. Just what I wanted.
