Pulling trigger on coilovers, pls look over my choice

I believe the KWV3 spring rates are 11/8. Might be on the softer side for track duty. They also require you to cut your top hats as well to retain the OEM quietness and feel.

Yes, I've been told kw v3 is 11 kg front and 8 kg per rear. I have them on my car and they are quiet and smooth for sure at any ride height I've had them at, although its not recommended that you ride "slammed" with these, which i don't anyways. I don't track so can't comment on that.

I have KW V3 FOR two years now. I have them set two clicks counter clock wise. about perfect for SoCal. I haven't tried any other settings except what is set from out of the box which was rough here in SoCal streets.

Greddy KW's I'm not liking them
Agree with the above. GReddy/KW from MIJ are much less than advertised MSRP and I trust KW’s valving all day compared to BC’s for the same price.
I do believe you can dial in the BC’s especially when mated with the Swift springs, but the moment you enter preload adjustability into the mix you need to be quite suspension savvy to know what you are doing.
The Greddy’s I daily two clicks from full stiff and rides great. I may go Öhlins some day but for the price I’d be tempted to go bags and it ride like a Cadillac since this car will always just be a point A to B vehicle, a fun one at least

Interesting.
Ive had cruise control set in the 110-120mph range up in Canada taking highway corners through the pass and never once felt uneasy about the experience.
I’d venture to guess your steering input issues are from the alignment. I punched it on a back road today and hit a small bridge connection at 80mph that nearly jumped the entire vehicle and they controlled the rebound no issues. Wasn’t anticipating that dip but handled it just fine haha.
The Greddy’s are merely a V2 KW with a galvanized shock body a higher spring rate, something people claim is too low on the V3’s for this chassis. V3’s have compression adjustment, but I doubt there’s more than a handful on here that have even adjusted/fine tuned it. It rides “smoother” in part by using the stock rubber top hats which doesn’t transfer as much road vibration. Similar to the stock LCA’s vs the RR ones.

Tracking with rates that low will allow the inside rear wheel to come off the ground. The OEM suspension does this on track, so a softer rate will only make it worse. Like most things suspension, they might feel good, but they won't provide mechanical grip when you really want it.

Thats why I will go custom builds by Figs or RR. They can help you get what you want and still perform.

These rates seem way to low for this heavy car.’comfort isn’t about low spring rates, it is about matching spring rates with the appropriate dampening and rebound (I think, I’m learning).

Even springs suffer this fate. Few spring brands actually measure out at their rated numbers, which is why Hypercoil is so popular in the racing community. You get the rate the box says you should. Once again, if you want an education in mechanical grip and performance, go here: http://farnorthracing.com/autocross_secrets5.html. The guy is pretty opinionated, but he's forgot more about suspension than I'll likely ever know and won a few championships along the way.

Who has put Swift springs 16/12k on kw v3?
I've had these coilovers on for a while and considering the upgrade. According to site vendors they say this is a common upgrade but yet have had anyone comment on the improvements

I recently bought the Greddy KW's, been running them for a month now. It just doesn't inspire confidence at highway passing speeds. Feels like the car is lifted and riding on tall skinny tires. In other words it will easily dart left or right with minimal input. Compared to my 2011 OEM suspension which felt much more planted at higher speed and stable ( 2 clicks in the front and 1.5 rear) The worse part is the steering feels overly touchy and not in a good way. Btw I have not done alignment as yet. My goal is slightly stiffer in the rear than OEM, other than that I was happy with the OEM set up. I plan to track maybe once a year. I use this car as my daily

I went from swift 16k front and 14k rear BC coilovers to Penske 18k front and 16k rear and all I can say is BC coilovers ride like garbage. If you ever make the change you WILL know exactly what I’m talking about. BC coilovers to me felt really harsh and never settled well after bumps. No matter how much I tried adjusting the damper for them it never felt good to me.
If you are more spirited than the DS series might be a better fit. There are no 2 customers that have identical ride preferences, budgets and setup experience. That is why we are here to help.
