We fixed it by swapping all 4 calipers for ones with pistons two steps smaller. For this Ceika kit, there is no fix.
One size kinda fits all. Well, physically fits anyways. Reading through the other comments it also appears that there is no option for a big bore MC like there is for an NA with the willywood, or 929 options. So 150% piston area notwithstanding, you can't even attempt to get it a little bit closer.
The funny part is, I was part of the group buy that had those made (as were many others) and it was decided as a group that the +20 offset was best because you could just add a small spacer if needed. People act like spacers are the devil, ****'s fine as long as you're not using janky ebay ones lol
Not sure how you fit them. At least with my current bilsteins I have a major space conflict with the spring. Inner lip of the barrel contacts the spring even with a 15mm spacer. Both front and rear. Along some of the travel it gets some gap, but at full droop it just doesn’t fit. The new coils are a bit slimmer at 3.15 inches OD for the spring.
How much tire poke do you have with the 295’s? The 275’s are a pretty mild stretch.
like Scaxx said there’s nothing wrong with spacers. I’ll probably have to have some amount of spacer but just want to minimize it. No issues if you’re hub centric and have extended studs.
and one last note, IIRC the jongbloeds have a much thicker lug seat, so the lug nuts already sit further spaced out from the hub. IMO extended studs are a requirement for these.
I could have earned the difference between these shocks and the Xidas by dancing on OnlyFans, had them delivered from SoCal, AND installed them in the time it's taken this thread to go nowhere...
The long awaited update you've been looking for is finally here. I have them installed now and have gotten an alignment done (after these pictures were taken.)
First impressions are good. I took the car up some mountain roads and they run very smooth on nice asphalt. Body roll is reduced because of the stiffer springs obviously. Grip is decent, it certainly feels more planted being significantly lower. At 14 clicks front (from full soft) and 10 rear it feels sporty (30 clicks total). Although with these settings it's pretty stiff on potholes and rough roads, a bit too much for road trips and casual driving. I found that running 4 clicks front and 0 rear is very smooth given the spring rates and is good for daily driving. For autocross I'll likely be running it stiff. Exterior facing components seem high quality. Everything is CNC Lathed or milled.
Install went smoothly. Fronts have minimal preload, just snugged up 2mm. Given the Miata's weight this leaves roughly 2/3 bump travel and 1/3 droop at ride height. For the rear, running minimal preload led to 2/3 droop 1/3 bump, so I snugged up the upper collars so I'm split roughly 50/50 bump and droop. I am 4.75 inches pinch weld to floor. With these settings, the stock wheels have no interference anywhere, however I'm not running fender liners on the front.
Fronts have ~90mm of shock travel excluding the bump stops, rears have ~80mm excluding bump stops. The bump stops are ~20mm thick and dense.
Fronts at ride height and full droop: Rears at ride height and full droop: The car as it sits: Front coilovers installed:
With the car in the air the 275/35r15's + jongbloeds barely clear the slimmer springs. I suspect that with a loaded suspension with bushings distorting and sidewall flexure there might be contact. In that case, I may have to tip in the tophats slightly for that little bit of extra clearance. The shock bodies fit through the FUCA like a hotdog down a hallway, as did my bilsteins. No idea why one of you said that altering the tophat pivot location would lead to contact there, there is plenty of room for adjustment. I checked the full travel without springs installed. For now it's not needed as I'm still rocking the stock wheels so I'm running the included non-adjustable tophats.
Overall, I'm pretty satisfied. I've ridden in, worked on, and driven plenty of miatas with coilovers ranging from no-name instagram garbage all the way to ohlins, and of course my bilsteins. These fit pretty much in the middle leaning toward the higher end. Given the price, they're decent bang for buck considering how much more you could spend on coilovers.
