DC suspension swap

When you guys swap DC shocks/springs, did you reuse the DA top hats or did you also swapped the DC top hats?

Reason I asked is because I swapped the struts and found out the rubber piece that goes under the DA top hats (front) didn’t fit the DC springs and now the ride is bumpy. Don’t know if that’s the cause of it.

Do DC top hats fit the DA mounting holes? Anyone confirm?

Thanks!

their the same. its probily bumpy cuz your shocks are bottoming out. when i put dc shocks on mine i had to adjust the front coil overs all way down and its still not as low as i want it. my back coil overs are adjusted in the middle and are tuckin tire. its because the rear shocks are like 2" shorter. id reccomend getting some extended top hats for front or da rear shocks

Hmm doesn’t seem much of a pro running DC/EG suspension then why do I hear alot of DA owners switching over to DC/EG setups?
I think my old setup feels better (Illuminas and Megan coilovers).

Generally people switch to the EG/DC suspension because there are more options available. Many companies will offer suspension for the EG/DC whereas they have nothing, or only limited offerings for the DA. Theres no inherent difference in quality or performance, it’s purely a fitment thing.

Thanks for clearing that up Colin. It was kind of a bitch trying to stuff the looooooong EG shocks into the forks. I’m going to ride it out and see if it improves. If not, I’m switching back to DA ones.

A bumpy ride is going to be an issue with bottoming out and/or improper spring rate/damping combo. So don’t think about it as being a problem that you switched to EG/DC suspension. Look at the specific changes you made. You said you originally had Illuminas and Megan coilovers. What shocks are you running now? How does their damping compare with your old shocks? What springs/coilovers are you running now? How do they compare to your old setup?

I’m running with the “new on the market” Raceland coilovers. The Vdubs and Beamer guys rave about these cheap coilovers so I had to try it. They only had for the EG so that’s why I got it.
There no damper control, only height adjustment. Spring rates are really soft, it’s like 150F 250R or something like that (can’t remember). I just hope they settle in nicely after a few rides… if not, I’ll try homemade extended top hats and go from there…

Chances are you just went from a good suspension to a shitty one. I’ve never heard of Raceland, but I’d be surprised if the shocks were anywhere near the quality of the Illuminas. And 150/250!??! I hope you’ve got those rates backwards, and even then those rates are really low if you’re looking for any sort of reasonable performance upgrade. I forget the exact numbers, but I think the stock spring rates are around 260f/140r.

Don’t expect suspension to “settle” over time. It should ride the same the first time you drive it after you install the suspension as it does the next week, next month…etc (with the exception of any additional changes you make and/or the suspension components wearing out over time).

What EXACTLY is the problem you’re having, cause from what you’ve said so far it doesn’t sound like anything that would be caused by lack of a top hat isolator bushing. And don’t say its “bumpy”, you need to ellaborate on exactly what’s going on and what about it you don’t like.

wow you used the da forks lol i didnt know you can do that. i used dc forks.

No I didn’t use the DA forks, I used the EG forks… sorry, didn’t elaborate on my other post.

Colin - after installation, I took it for a ride and it was bumpy as hell. It seems like the front is trying to plant itself on the ground but the back is trying to push it up it down so it doesn’t settle.
To sum it up, front and rear seems to be fighting against each other thus not making the car settle down. Maybe you’re right though, I might have switch the springs from front to rear and vice versa.

I’ll try swapping them and see how it feels.

If you have the stiffer springs in the rear then you installed them wrong. I originally just thought you may have typed that wrong… 150 lbs/in is WAY too soft for the front, as I stated before, it’s softer than stock. Generally you want a stiffer spring up front because most of the car’s weight is up front. If you put a soft spring in front and a stiff one in the back I could see how the rear spring would push the rear up and down in turn causing the front to get some residual “rocking” front to back. This would also be made worse by poor shock valving.

With that said, people often run a stiffer rate in the rear, generally only on race cars though, not street cars. And on those cars you’re running very high spring rates on both ends. Comparing a rear bias setup like that to your situation is like apples to oranges.

Thank you sir! Sounds very reasonable ^^.
My car is only used for DD so switching springs
would be the better way to go. I’ll try that out and
see how it goes. Thanks!

for those of you who are not familiar with “RACELAND” coilovers… its a new company that offers “AFFORDABLE” coilovers… (meaning low quality) a buddy of mine has them for his scion tc and paid only 350 dollars! the quality sucks on them but he doesnt care because he just wanted his car “SLAMMED”… (idiot) so if you are wondering why they feel shity its because of the quality… YOU GET WHAT YOU PAY FOR. stop spending your money on low end products and save up for a quality one… DO IT ONCE AND DO IT RIGHT… now you are going to have to sell or return those and buy some good ones… double the work. and as colin said those coilovers are no where near the quality of illuminas. http://www.racelandus.com/c-22-coilover-kits.aspx. :down:

i’m guessing this is a good thread to ask this question instead of posting another thread…

i was reading around…i know as far as the front goes…all you need are the DC forks for DC/EG suspension to work on our DA/DBs, but as far as teh rear goes, i was reading somewhere else where the guy who had a eg/dc coilover setup was unable to get some spacers machined for the rear coilovers to make it work on his DA…i was always under teh assumption that the rear EG/DC suspension/coilovers were pretty much a direct swap, just a shorter strut…am i correct?

Yeah EG/DC suspensions are a direct swap with the exception of using EG/DC forks for the front. It’s best to go with an adjustable coilover setup since the EG/DC rears willbe lower than the DA’s.

our shock bushing width is exactly the same as the DC chassis.

EKs are the one that has a shorter width and they need washers if using EG/DC rear shocks

ok, thanks alot fellas, i appreciate it.

Old thread but I am interested in the mention of a spacer to go on the DC coilover to make them work in a DA. I have my cheap coilovers at maximum height but the car still sits too low in the rear.

I was thinking of getting a 2 inch spacer machined to bolt on to the top hat with a couple of studs to go into the OEM mounting points, somewhat similar to a hub spacer. Anyone forsee any issues with doing this?
