Cosmo brake upgrade
- Thread starter DMRH
- Start date
Package un-packed & photographed. Here are the raw components.
Note: the 330mm discs are a "Full-floating" design to save unsprung weight.
I shall attempt to get them fitted to the Cosmo in the next week or so as time is short but shall manage something.
I'm keen to weigh these parts & the factory parts coming off to work out the difference.

Quite a weight saving................
Standard front strut/spring combo = 7kg ea
Custom front strut/spring combo = 3kg ea
Standard front calipers = 6kg ea
Custom front calipers = 2kg ea
Thats a lot of savings in "Un-sprung" weight that will mean greater handling abilities..................(wiggle)

Well, last weeked was a good one with most of SUN devoted to fitting the front shocks & brakes to the Cosmo.
We rolled the Cosmo into a mates garage. 12hours, Pizza, beer & plenty of distractions later the work was completed.
Here are the pic's
01. Starting with the standard 280mm single pot brakes.
02. We cut the backing plate with an angle-grinder as I didn't have a 32mm socket to remove the hub so it had to remain there, in very cut down form at least.
03. Fitting the caliper adapter. Both bolts using "Lock-tight" for safety
04. The kit comes with plenty of shimes to get the alignment 100%. In the Cosmo case. A single 0.5mm? shime was required. Lock-tight applied after.
05. Fitting the disc rotor is easy
06. Time to bolt caliper into place. Caliper bolt secured with Lock-tight
07. Braided lining flexible hose fitted & mounted via "supplied" bracket on shock tube. Pad "rattle-plate" fitted to back of caliper.
08. Job completed & dont they look the part. Front shocks where a very simple Install too.
09. 330mm discs tuck into the 19" wheels quite well I thought. Just the eye-candy factor is worth it already.
How do they feel......?
Didn't get the chance to properly test them. Drove Cosmo 5km back into garage at 60km/h - 80km/h speeds trying to bed pads in. Will test further next weekend or so after rear shocks are fitted.

G'day. Here are the pics of the rear shocks getting installed. Installation of the rears was seriously easy once the interior was removed.
The rear parcel shelf had a couple of holes bored out in them but not through the top fabric. I then left the adjusting key inside the strut if I ever need to adjust it again.

Took the Cosmo for a little drive last night to give the suspension & brakes a test. Started raining (typical) so couldn't go too hard.....
First the suspension makes the car feel different in two ways.....
1. The considerable reduction in Un-sprung weight
2. stiffer springs & struts
So the car turns in sharper & just feels plain safer through a corner. the added weight of the Cosmo means it doesn't buck & bounce around like fitting these to a lighter RX-7.
Second, the brakes feel about the same at normal driving speeds but do have a definate "added bite" to them at higher speeds. 100km/h plus. I think the pad material they gave lacks the "bite" I expected or am I expecting too much...?
Perhaps I can change the pad compound as they are the FERODO brand of which I can easily source here in Sydney. More driving will tell a better story
