Coilovers on a Q4

Has anyone put coilovers on a Q4? What are your pros and cons. I’ll also take those that have put them on a Q2. But not really interested in those that have done it to a Quadrifoglio.

Yes. On our Q4 Ti Sport. KW V3.

I set mine up to be around same height as QV 2017. Rode very nice. Handled well. Comfort still there but you do need to lower setting to almost 1.

I liked it. More compliant and less front end lift or bounciness. We also corner balanced the car for best results. Picture below, we adjusted the rear a bit higher than this picture for proper handling. It came out well and looked good too.

Is that your setting? 1 all the way around? Both compression and rebound?

Tradeoffs:

Loss of adaptive shock system.
Loss of travel.
Loss of ground clearance.

IMO for Q4 coil overs with the adaptive system and with the ability to adjust the suspension up (for winter) or down (for summer) seems much more functional to me.

Tradeoffs: There is always those.

Loss of adaptive shock system. - Depends if you have it, some may not think of it as a loss.
Loss of travel. -Depends on how low you go. I stuck with stock Qv height on our test ti sport Q4.
Loss of ground clearance.- Depends on how low you go.

IMO for Q4 coil overs with the adaptive system and with the ability to adjust the suspension up (for winter) or down (for summer) seems much more functional to me.
- Not available for this car. It's manual height adjustment and manual adjustment of dampening etc... The QV has the DDC system that works with the adaptive suspension.

Modifications don’t void the entire warranty. They only void the warranty on item that you’ve modded. So in this case, the suspension.

2018 is the worst year to buy stock springs. All the models were an inch higher than the 2017. So you may not see a difference at all when compared to your 2019, when they came back down a bit. If you want stock springs, buy the 2017 springs. That’s when they were the lowest.

Even on the AWD models? I thought they were raised a bit compared to the RWD versions. And i work at a Alfa Dealership, and trust me, Mopar will void your entire warranty for any possible reason they can. I asked my Mopar rep and she still hasnt answered me on what i can do with the springs without voiding the warranty

IMO in an ideal world Q4 with ability to adjust the suspension about 1" up or 1" down would be great. A manual adjustment would be good enough for me. Put the snow tires on for winter and hike that skirt up, put the summer tires on for go fast season and drop it down.

I suspect that the height of Q4 is there partially to keep a reasonable amount of suspension travel. The front shocks are really cramped for space due to the need to straddle half shafts.

Now where are the Ti springs and hubs for my car?
Ti hubs especially reduce unsprung weight, reduce brake heat transfer to the hub bearings, and are corrosion resistant.
Ti springs save a lot of weight (Ti coil springs are about 40% of the weight of the same spring rate steel coil spring) and having bright bare metal springs has gotta look good.

Manual ride height adjusters are a massive PITA and the change in ride height changes wheel alignment.

What is ideal is the KW HLS system which is basically a height adjustable hydraulic spring spacer (otherwise known as a hydraulic button jack). So you set your ideal ride height and alignment and just raise the car briefly for the rare snowstorm or obstacle ... Of course it's lol expensive for a not really good reason though.

HLS is rated up to 50mph (which really means "hey you have less than ideal alignment so don't push things") so it should be fine for a any snow storm where you have to lift the car. Once the hydraulic rams are open and valves are shut there is nothing that's going to wear out from extended trips.

Air cups are similar and a fraction of the price, but air is less optimal then hydraulics.

Using the coilovers ride height adjusters with the spring not compressed is just a cursing match. You need to make sure everything is clean, try to lubricate the threads, and then start cursing. It's also a pain to dial in a specific ride height as you need to work with the car jacked up, make your adjustments, let the suspension settle, and then recheck the ride height... and then restart the cursing match.

The KWV3 would be way too expensive for me anyway the ones I’m going to try. We’re about 1000 for the set. Hopefully that does the trick if not the next step would be a frame stiffening kit. Hopefully I don’t have to go there if you’re working on springs are you going to work on shocks as well, I’ve heard BM. I’ve heard Bill is going to be getting rid of the B6 for the alpha which doesn’t leave much for an aftermarket stiffer shock. Then they come out of the factory. I haven’t driven a 2020 or newer, but hopefully they are firmer and without as much wobble and sway as the 2019 has , and again 30 posts have been invested in my question and not one viable suggestion

Maybe proofread before hitting that Post reply button so people don't have to wonder what the F you're talking about.

The Hiro coilovers went on my Q4, and have proven to be a good investment. The ride is improved, handling in tight cornering situations is much better. My car is now. almost as much fun to drive as my 18 with the electronic shocks. The most noticeable improvements are no more road wobble, she tracks straight, the front no longer rises with hard acceleration, nor dips with hard braking. she snaps out of tight corners, and adjustments are easy to make. costing far less than the electronic shocks on the 18, they are well worth it if you want to get more out of a traditionally sprung Giulia.

Good info. Hope you get decent longevity out of them.

got the rear ones on, didn't make a huge difference, but no question the car handles much better than stock now. time will tell how well they wear. overall impressed with the quality and customer service of Hiro, regardless of how people with no experience with them feel. My car now drives and handles like it should!
