That is good to know. I'm not sure who manufactured mine, but they are bolted on at three different points. I will probably pull them off now

Im at either 3030,3031 or 3037 race weight. As you can see in the pic, the last digit of the scale display is kinda fubar. Scale is at Atco Raceway in NJ.

I only had the driver seat in for race day, but i do not have any lightweight race seats. They are knock off recaros, similar to a 6LE seat. Also have a 6LE Harness bar and harnesses in.

On my car I had an iron lsnext at 224lbs and switched to the aluminum which was 115. It hurt me more than helped because I dropped 2.5% nose weight so the car wheelied all year.
My glide is a fti level 5. aluminum valve body. 114lbs without fluid.
Rear axle was a quick performance at 167lbs. Waiting on my new narrowed MWC to show up and compare.

A spooled S60 is not as heavy as people want to think it is. 15lbs over a aluminum case 9" tops. I haven't weighed my car in sig on scales yet but in calculating everything i removed I must be at around 3050 without driver.

BlackSS4thgen

how much did your s60 weigh?

If you're gonna weigh these rears you have to include the tq arm or it will be misleading. A fab 9 will weigh less and decidedly less in a fair comparison partly due to the design inclusion of the tq arm.

My mwc fab 9 only weighs about 10lb more than the 10bolt including tq arm if that. The mwc tq arm is lighter than stock to as with the transmission crossmember. So unless your ditching the tq arm and all the brackets that go with it then it's not apples to apples.

I bet the entire package could weigh less with a mwc fab 9 vs a 10bolt and not using a spool. I wish i woulda weighed all of both.

Launch

167 lbs complete with caliper brackets, no rotors or calipers. 35spl axles and spool. I think if it had a posi unit it'd have to be closer to 200 lbs. Spool removes a lot of weight on these things because of the size of it.

Launch

lol that's too weird. I hadn't noticed this until just now when I returned to the thread. Anyone else want to confirm the weight of their 35spl S60 with spool (no brakes)...

Launch

I just did a search to see in case I got it wrong somehow. I found this....

So I must have weighed mine correct. He is saying above that his S60 was 196 lbs with the truetrac and the spool saved 32.8 lbs so 163.2lbs. His probably is shortened more? Mine is shortened 1" overall from stock length (1/2" per side).

Launch

Is your S60 a spool or s-trac/ truetrac ? Your car does seem heavy for what it has. Even my th400 is no heavier from memory than a 4l60e.

Launch

How I came to the 3050lbs no driver number..
Backseats/seatbelts all gone
Drivers electric seat base swapped for manual base
Underdash A/C heater unit all gone
Airbags gone
Momo steering wheel and adapter
Bunch of wiring and relays removed
Both internal bumpers removed
Midwest front bumper support
Front sway bar & brackets all gone
Windscreen washer bottle and radiator plastics gone
Gutted all the insulation backing from factory carpet
ABS and cruise control unit all gone
No spare wheel/jack
Factory amp/speaker removed
All heat shields removed
Weld 15x5 fronts with 185's (Weld rears with qtp's not much different to stock wheels)
10" torque converter (my t400 weighs same as 4l60e no converters, but 10" converter much lighter than stock 4l60e one)

I started with using the weight of a 99 base hardtop ls1 car as mine is ls swapped. I'm sure there was more things removed at the time that I weighed that I'm now forgetting. Added 17lbs for spooled s60 and 22lbs for UMI bolt on subframe connectors. Next weight removal for mine has to be a glass hood and lexan front and back window to recover some of the weight added when I install a cage. Also hopefully a pair of race seats with harness can end up lighter than the stock front seats. And also remove the interior door panels for some flat carbon or aluminum. I'd like to keep the car at around 3000lbs no driver but I wish it was lighter without having to start cutting pieces out.

Now that I think about it more ,TTur1996 yours seem about right with the weight with what you have because of your cast iron block.

How is it still that heavy?

idk what type of diff is in my 9" but it's not much bigger than a spool.

BlackSS4thgen

lol yea. no doubt. What is the chances.

That is with 40 spline and their tq arm mount which is like 11 pounds. The aluminum moser bolt through with pro gear is 54 pounds and strange non bolt with 28 spline strange gear is 52 pounds.

I asked because I weighed an s60 a couple years ago with caliper brackets and it was 220 pounds. i have no idea what diff or axles it had or even how much fluid was in it.

Launch

If you mean my car? ..maybe it's lighter. I won't know until I weigh it which I haven't done yet.

Launch

I hadn't even seen you mention the weight of your 9" until afterwards. "Strange" coincidence for sure I weighed mine without oil so add another 5-6 pounds.. 172-173 lbs. What you weighed had to have an s-trac or truetrac in it. No way it had a spool in it. Because of how big the carriers are in the s60 when you go to a spool it removes a heap of weight, much more so than a 9" spool versus posi.

I did a search to see if somehow I got it wrong even though I know I couldn't have, and I found user "studderin" on here say his was 198lbs with truetrac (no brakes) and then lost 33lbs going to the spool. Now I'm betting his 198lbs was without oil so add 6lbs = 204lbs and his was possibly shortened.

220lbs seems excessive but if what you weighed was stock length and had oil in it.. and maybe one of the other carriers is slightly heavier than even a truetrac, I can see 220lbs. If I ever have mine out again i'll put it on the scales with oil and take a pic. I know it'll be 172-174lbs with oil. And a 9" for these cars with spool no brakes are what 145-170lbs depending on who's housing it is. There's really not that much in it when both are running a full spool.

oh....i thought you said it weighed 3050 .

Launch

No I weighed everything I took out and put back in and just figured it must be around 3050, after finding the kerb weight listed online for a base a4 hardtop ls1 car. I haven't actually weighed the car yet.

Launch

That's how I figured out mine. So from what you've said, yours must sit somewhere around 3125lbs.

Now I'm kind of agreeing with user: TTur1996 on how are some of these cars mentioned so light.

Well i have a ht car also. As i stated last time on the scales it weighed 2993. But it still has almost everything you took out lol. I think i did have the jack/spare out of it and the air bags are gone. I can't rememberif the front bar was on it.

. All seats/abs/sound deadening/seat belts/full monsoon stereo/full size battery/full hvacstuff was all there. I think it had about 1/4 tank of gas to.

Your car should be way lighter than mine unless you have alot of safety equipment in it.
