Default Coilovers: KWv3 vs HKS Hipermax

Coilovers will be my next upgrade to my '11 F and I'm primarily considering the KWv3s and HKS Hipermax IVs. I don't track my car, and while I value sporty driving (mountains/canyons, etc), I'd like to add a bit more comfort to the ride. I don't expect the car to ride like an LS, so no need for the "if you want comfort buy a different car" responses. I'd just like to minimize some of the thumping over road imperfections. My '11 suspension is currently stock except for the USRS. Has anyone driven/ridden in F's with both of these setups? What were your impressions between the two?

There are a few members here that have the HKS Hipermax IVs, hopefully they can chime in with their experience. From what I remember they like them and they are more compliant than the stock suspension, they are around $2000

The KW v3s are probably the most widely used coil over set up on the ISF maybe next to the BC coil overs. They seem to be a favorite among members here and soften up the ride. You can find a used set usually around $2,100 or so......

I have the HKS.
Between these 2 choices you need to ask yourself what type of ride you want.
KW are soft for the ISF but perfect for someone who daily drive and doesn't track the car.
HKS are stiffer but very well dampened. For myself I could've accepted even stiffer but overall happy with the HKS. Can't even consider the low rates of the KW.

I also have HKS thanks to Max's recommendation. I found them to be a major improvement over my stock 08 suspension. Currently I have them dial closer to stiff (between half and full stiff) and it is very comfortable. I daily drive my F in all seasons

Edit: i just adjusted the compression on the KW's and comfort is much better. however, here in SoCal, i don't think anything can help the IS F. that's my experience so far.

I know that the Hipermax IVs are a good setup for the money (I have actually used the Hipermax IV SP on my own vehicle when testing different single adjustable dampers). However, if you're looking for comfort and/or flexibility then I would definitely go with the KW V3s. They are a 2-way as well so you can adjust the compression damping to your liking independent of rebound. Essentially you can back down on (soften) compression without also softening the rebound damping, making the car bouncier and/or floatier (which is what typically happens when you run rebound too soft for a given spring rate).

On pretty much all single adjustable dampers the compression damping is pretty much fixed and the **** is to adjust rebound damping. Almost all of the consumer grade single adjustable dampers advertise the one **** being tied to both compression and rebound in one click but this can be a little misleading- anytime you adjust compression or rebound in a single, double or triple adjustable damper, it technically always slightly affects the other in a phenomenon known as "crosstalk". The degree to which a damper does this this varies widely and generally speaking you can expect a higher end damper do it less than the less expensive/lower quality ones. Just something to consider.

If you are interested in either PM me for pricing! We will be running a sale on the KW V3s soon but I would be happy to extend that discount now if you don't want to wait.

For the price of the kws you could get slightly used Penskes if performance is your priority. They also come with proper spring rates for the isf.

I feel like the BCs with 16/12 Swifts are the top option on my list, all things considered. Even the almighty Penskes have their detractors among those that have them--I think there is a set for sale due to the harshness of the ride. The KW rates seem way too soft by the numbers.

The penskes are not harsh but they're a bit noisy over NYC roads. If you don't live in the NY metro area I'd definitely recommend them. When I took them to VA and Pennsylvania, they were great.

Moderate track work? That's definitely an understatement from the likes of you, my friend!

I have the HKS Hipermax IV GT's and I love them.

I had Swift springs on stock suspension for a little over a year before I switched to the HKS, and I have zero regrets.

Install was easy, no need to take apart the factory suspension, and modify and factory parts like KW.

Wouldn't the Greddy coilovers be more comparable to the HKS than the V3's?

I was wondering the same thing. Does the shock body valving have more affect on the ride/handling than the actual springs? It seems like Greddy may have changed out the springs (more stiff) for the IS-F application rather than developing a new coil over system. Correct me if I'm wrong but, would this be the same as taking a BC coilover for a x250 and then simply swapping a stiffer spring on it? In any case, I gave up on buying the GreddyxKw but wonder if anyone else bought it. Feedback would be great as they are priced well.
