Did you end up with a negative rake situation where the rear was lower than the front with your Swift springs?

Hey what year was your car? And did you go to Coilovers or a different spring with the 20's?

These were the spacers I used: https://www.autozone.com/parts/suspe...30_0?rrec=true
Not the easiest to fasten inside of a spring but it did the job.

Ok thanks got it. Used those as much as 15 years ago on cars.

I still have the Tanabe springs myself and have not yet installed because I am still torn between the Swift and Tanabe springs. I really don't care that the Swifts don't really drop that much as I have read many say. Like many I just still would like to know which ride better more like stock with the most comfortable ride? Anyone, many that have them???

why didn’t you consider RS-R’s. Any reasoning? I’m torn between those and the swifts. Especially after saying a few people mentioned that the Swifts ended up a little lower in the back giving a negative rake which I really do not want

I saw a post a while back with the Tanabe and the Swifts uninstalled side by side piced. One looked taller and appeared that it had more travel to ride smoother. I thought the RS-R were suppose to be lower and rode harder. I want the closest to a soft stock ride.

having to add those spring helpers like the guy posted from AutoZone is definitely going to make a harsh ride. Those things are kind of sketch to begin with. I’ve been so on the fence about this because of the Swifts potentially being lower in the back that’s why I’m leaning towards the RSR‘s. I was extremely happy with RSR‘s on my 3IS 350. Granted they were only about half downs but they rode better than stock in my opinion

I believe this issue only affects 2016 and newer. And looking at the specs of the comparable RS-R’s There is a greater drop in the rear than the front on 2016 models and later with the same springs for both chassis codes.

So going with either RS-R's or Swift, a lower rear stance is inevitable so no other real quick alternative than using spring spacers without having to go the route of coilovers. I don't ride in the back so a "harsher" ride isn't a problem for me in using these spacers

yours is a 16+?
did you consider getting silicon spring spacer?
you can literally get a quarter inch or exactly what you need and maintain all ride quality

1/4"?? The difference between the front & rear was 3/4", the silicon spacers you're referring to wouldn't have done the job. It's been about a year now, I made the right choice and the ride feels fine. For anyone else that's looking to remedy this same issue I recommend the spacers I used.

They silicon spacers come in up to 3/4” and are what the factory part is just thinner. It’s the perch the spring sits on. Ask any mechanic which is the correct solution and more importantly the safe one. Those things you used are notoriously dangerous and change the spring rate which will chew up the rear shocks. I would highly advise against them. We have high end luxury cars. Not G-Body GM’s from the 80’s that you throw get to parts at

it sounds like your springs weren’t installed properly to begin with. 3/4 is a major difference. Like they forgot your isolators or perches, or your fronts are rotated beyond the insert on the coil perch. The other folks that I’ve discuss this issue with that have 16+ models had no more than 1/2 or less.

I recently installed swift springs on my ‘15 Gs and notice the rear is lower than the front. I agree with you on the silicon coil perch… I would NEVER use those spacer on any vehicle. So I’m curious if you’ve purchased these silicon spacers for your car.. Did you just go with slimmer front perches? Thanks
