Stiffer, more stable but not lower.

[domingo]

Hi,
I'm looking for suspension upgrade option but not the lower option. Bumpy roads, high speed bumps, and steepy garage exit gets me away from some stiffer spring due to -30mm drop.
Maybe one of you guys tried something that improve handling but dont make car much lower. Probably -10mm would be fine.
Spacers and sprut bar are already installed.

I’m also interested in improving the handling without going lower. I’m personally very happy with the stock ride height and ride quality. I’ve got wider wheels/tires and strut bar, and I’ll probably install sway bars and call it a day.

PS - I don’t track the car, just occasional canyon runs.

Front and rear sway bars would be an easy way to imrpove roll stiffness without making the ride much harsher. Maybe start with just a front bar (I think the rear is a bit of a PITA to install).

You need to do front and rear together otherwise you will upset the balance of the car. Stiffening the front end will cause more understeer if nothing is done at the rear.

KW v3 coilovers are a good upgrade and can be set to only drop 15mm in the front

Bigger F/R sways make a world of difference in reducing body roll + improving turn in. I hammer my car over some country backroads that sometimes have potholes that want to swallow my car, and I appreciate keeping my ride height stock at this point.

On a front heavy car like this a front bar will give you the most bang for the buck in terms of roll stiffness. Sure you may add a bit more understeer but on a tail happy car like this it's not a huge deal, it's easier to drive around push in sweepers than it is to drive around tail-happiness in transitions.

I wasn't happy with the body roll either, so I first installed the Euro-spec Eibach lowering coils (20mm drop f/r). It made the car more stable but didn't tighten the rolling up as much as I wanted. I installed some adjustable sway bars and now the car is perfect. Upgraded sway bars are the way to go.

Well...
Justed clicked the Eibach sway bars kit.

51% front bias is front heavy? Adding front roll stiffness will not make the car pleasant to drive, without balancing that in the rear. There have been a few posts of people doing that and then complaining about understeer.

Get a good alignment, add some front camber if possible. Little bit of toe in on the rear (.10) and zero toe in the front will keep it stable. On stock PSS tires the car is a tail happy pain in the ass yes, but roll bars are not fixing that. Swapping to better tires the car is quite stable and happy even with stock roll bars, would it be better with stiffer bars? Absolutely but if you arent willing to do front and rear I wouldnt do just the front.

Agreed that tires and an alignment, especially if you get adjustable FLCAs for adjustable front camber, are highly effective, and that getting a f+r set feels much better.

I think what stops most people is the cost compared to a front sway bar.

Coilovers with adjustable ride height will get you there.

Here's some of the most handling focused coilover options out there:
Ohlins Road & Track
KW V3 (Front: 0.6-1.4", Rear: 0.8-1.6") or DDC (Pairs with factory dampening control in Sport mode, same lowering range)
JRZ Coilovers

For comfort but balanced handling, the new HKS Hipermax S coilovers also seem very promising - designed for a smooth ride with lots of bump absorption, but good handling characteristics.

Stiffening components:
Cusco Power Braces + Sway Bars

SPL's suite of suspension and alignment hardware can help you dial in your ideal handling specs with a good setup by someone who knows what they're doing.

IIRC, the KW DDCs are V3s with the plug and play adaptive suspension. These feel great, and as you mentioned, you can minimize the drop.

I was very impressed in the car after alignment, hks adjustable springs, rt660s (275f/295r). I only lowered the car by 1/2 inch from stock because I dont feel like scraping on everything.

Turn in was sharp, entry/mid corner was stable, and getting on the throttle gave me the ability to use the rear end to drive the car out of the corner. I was originally thinking I was gonna need roll bars and coils but after having this setup im not going to change anything besides some FLCAs to add a bit more front camber as my tire temp was not as even as I would like across the tire. If I get into TTs that opinion might change but for track days a few times a year its completely sufficient.

52/48 is what I've read.

AFE themselves recommend going to full stiff on the front and full soft on the rear when you put in both bars, so I don't think going to a slightly stiffer front bar alone (as a starting point like I mentioned) would add a ton of understeer.
