BC Racing Coilovers

[AUZJDM]

This weekend I will be putting a set of coilovers into my NB mx5, I was just concerned about wether I need some spring compressors? not sure of there is enough room too drop the shocks out front and rear with the general flex of the arms.

Cheers

You shouldn't need spring compressors.

If you haven't done it before, I recommend the "Long Bolt" method for the fronts - just Google it.

Out of interest what BC Racing coilovers are you using?

Won't need spring compressors. Use the long bolt method. There should be plenty of room to get the old assemblies out. It helps if you have a second person apply leverage to the hub or LCA as the other gets the shock assembly out.

Because Coilovers are adjustable in height you should be able to simply wind them down as low as they go, install them, then wind up to what height you need/want./

If you are using the External Reservoir model you need to ensure that the brackets holding the External Reservoir are loose before you adjust the height. I have been using the External Reservoir model for about 4 months and the only negative feedback that I have is that the settings are not progressive.

The difference between F/R Bump: 25/10 Rebound: 20/18 and F/R Bump: 15/10 Rebound: 15/10 is enormous. I had the softer settiings on a club run them switched to the harder settings for a track run and the handling was so much better on the harder settings.

At the moment I have not changed the settings back, however I'm not driving the car as I'm in WA at work.

There is a good review here http://www.iwsti.com/forums/gd-suspension-handling-stiffening/168885-bc-racing-er-series-coilover-comprehensive-review.html

The instructions are rubbish and look like some-one's used a half-arsed Mandarin->English translator to produce them and never bothered to get a native English speaker to actually read them which is a pity because the hardware is "top-notch".

Here's some decent Height & Camber adjustment instructions I found when installing my BR series coilovers:


You'll need 2x21mm wrenches to do the long bolt method - if you're in Brisbane, send me a PM and I can lend you mine which I bought specifically for this job and have been used by others for the same job.

You don't need to remove the splashtray when you install the coilovers but it can make it easier to slide the long bolts out since it gives you more room. When I did mine and helped Davex3 with his, our passenger side long bolts would not slide out easily so we ended up using long bolts and punches to tap the log bolt out with a hammer; additionally I slid the long bolt by hand and ripped a nice chunk of skin on my thumb against the splashtray due to the cramped space available to get my hand on the long bolt.

If you haven't done them before, it will take a while so allow at least 6 hours to do the job and set the coilover height.

Ill be using the BC BR racing series ones, I was mainly concerned about taking the stock suspension out but that long bolt method looks the goods, if anything I have a few mates coming too lend a hand.
