to those who think you wouldn't notice the difference, then throw an extra 60 grams on your car and run it back to back in a blind test with and without the balast, you will notice it immensely
especially if you lighten up the drivetrain.

im glad to see my post is bringing in so much info!
what else can be done besides the shafts, ti screw kit, and ti pillow/pivot balls?
and for safe practice, should you weigh the car with bald tires? so at the end of a main, and your tires are gone, u meet the minimum?

Depends what kind of tyres you are using too!
If you set your car up using the Kawahara tyres for example, and the car is 1730.
Then you get a good price on the twister light weight rim ( or ATS) tyres and switch to them, you will need to add 15g to the car to keep above the legal weight as this set is 18g total weight saving.
So make sure that you weigh the car with the tyre type you are going to use & if you change, check the new tyre weight!!

any tips for getting more mid corner steering? my car turns in great under brakes and exits corners well but I find it pushes when off throttle. Thinking castor/roll centre might be the next change. I tried adding another 1mm under the front upper arms but this didnt make it any better

-- 2 holes piston damper at front, 1 hole piston damper at rear <---- this is my second try
-- lower shore at front tires, eg. 37 front, 40 rear <---- this is my first try
-- one grade softer spring at front, eg. purple spring at front, light blue spring at rear.
-- less downstop value for rear tires, eg. 3, instead of 5 ( 5 is the original downstop value based on factory setup ).
-- shortened wheelbase by 2mm by shaving rear lower suspension. <--- my 3rd try.
Don't change caster and roll center, coz it's gonna make different handling feeling, ...... possibly change the way you drive the car.

Try one or two of the following :

kit pulleys, spool, 30k diff. Track is tight and med-to-low grip but quite abrasive hence the 42 shore rears. Also running 50wt oil front rear with stock pistons drilled out to 1.2mm. As I mentioned the car is very quick and handles nicely but I do notice I'm scrubbing a bit of speed off mid corner so just want to make a subtle change to get a bit more grip here.

Are you running the box setup? If so I always struggled with mid corner steering with the stock setup. I tried all the above advice and they all helped but not enough. The RRR's would whoop my ass in the corners. I checked other car's setup sheets and they all ran higher roll centers (pins up) in the rear so I tried it and the car feels great. If you haven't tried give it a shot.
