Wish we could get this thread moved to the racing section and pinned to the top where it belongs!

 

Not a problem....

 

 

Charcoal canister and Evap pump/bracket with interconnecting hose - 6.1 lbs.

If you want to get crazy with it, metal Evap line running full length of chassis - 1.0 lbs.

.

 

Does anyone have the weight of the stock fuel tank?

 

Didn’t think to do it, but I’ll weigh mine later this evening for you.

 

Cheers!

 

Empty 2005 S1 fuel tank with internal siphon hose (no pumps, level floats, etc.) is 25.5 lbs +/- 0.25 lbs on my digital scale.

 

Thanks Mark!

 

2005 S1

Full set of oil cooler metal lines, hoses, banjo bolts, fasteners, etc. - 10.5 lbs.

Oil cooler with shroud and mounting bolts/rivets - 4.6 lbs each x 2

Oil cooler mounting brackets and fasteners - 1 lbs/side x 2

Oil filter pedestal; bare - 0.6 lbs

First time posting for me but using the great advice for a while.

Sorry I have missed it but after the weight for:

a rotor
rotor housing

Looking to import some parts from us for a rebuild - much cheaper but depends on postage which is weight driven.

Thx in advance.

jjaffahh

 

Both front seat belt assemblies with all hardware, trim covers, etc from a 2005 S1 - 12.75 lbs.

 

No worries.

Will do.

i wasn’t after costs but weights.

 

Factory roof: 19.6lbs
Marsh composites Dry Carbon Roof: 5lbs 3oz

Per Trackjunkie; his slightly used OE clutch assembly was 16.2 lbs, so figure maybe 17 lbs new with factory PP bolts. Which the OE flywheel is usually 17.1 - 17.2 lbs.

That’s roughly 34 lbs total assembled to compare against a race clutch/flywheel assembly, but don’t forget to add in the 3.6 lbs counterweight that most non-OE flywheels require for proper balance.

Just the center Radio/HVAC control panel only is 1.4 lbs
.

 

Sorry, some of these things I didn’t want to separate fully, mostly was trying to get an accurate unsprung mass number for my car. Not going to post everything since I have some custom stuff like brakes, speedway swaybar, etc. that won’t be applicable for anyone else:


S1 Front Upper Control Arm with Speedsource delrin bushings - 2.6 lbs

S1 Front Lower Control arm with spherical shock bearing/aluminum carrier (factory bushing is heavier) and Powergrid endlink attached - 7.9 lbs

S1 Front upright with wheel hub bolted-on having 2.75” ARP wheel studs, & Motorsports ball joint camber bushing - 16.3 lbs

IGN-1A ignition coils are heavy, (4) of them bare weigh 1648 grams/3.63 lbs plus the mount & hardware weight on top of it

can’t recall ever seeing the OE ignition coil, but they’re very light in comparison

 

The bracket with nuts:

 

Thanks BC

 

I have the dashboard out of my car and decided to remove the A/C evaporator assembly while I was in there. It consists of the actual evaporator core, the inlet and outlet pipes which are wrapped in butyl tape, and two allen-head bolts. Total weight for the assembly was just under 5lbs.

 

thanks John, was always curious to confirm that

just to be sure, you kept the rest of the HVAC assembly/heater core/fan/etc.?
.

 

Correct. The main HVAC unit even with the heater core still installed weighs almost nothing, it's very surprising. The blower unit is also very light.

 

anybody have a loose eshaft laying about they can post the weight on?
