Someone made a list earlier in this thread, I've modified it a bit:

- Both Hollow shafts #33401 & #33402
- Graphite front and rear shocktowers #73089 & #73090
- Full set of Ti screws (#Z368 for the HPI set, Yokomo also makes machine-thread Ti screws, and you can use aluminum screws in low-stress areas to save some grams)
- Titanium turnbuckles (two 4 x 40mm, two 4-40 x 24mm)
- Super chassis #73924
- Light top deck (#33408, must order from Asia or just remove the receiver box, see below)
- 0.8 module gearbox #87173
- Heat sink engine mount #33405
- Graphite suspension arms (not sure if part # is different, the arms have been updated since initial release - if you have 2 sway bar mounts on the rear arm you have the new arms)
- Titanium pivotballs (#33426 for 2 or #33427 for 8)
- Titanium hingepins (not sure of brand/part #)
- Graphite steering drag plate (not sure of brand/part #)
- Graphite lower front suspension mounts (not sure of brand/part #)
- Graphite side brace #73104 or #73105 (thinner version)
- Lightweight HPI battery (#33410, order from Asia make your own, see below)
- Remove upper battery cover
- Front One-way #75026
- 9550 steering servo, 3003 throttle servo (or any low-profile servos)
- Airtronics (Sanwa) 211 RX or and micro-size receiver
- don't use the aluminum rear brace or upper deck mounts (that's my suggestion)

You can also save 40g by making a battery pack from 5 AAA NiMH batteries in 2 + 3 shape instead of a normal battery pack. Mount in the normal position.

You can also mount the antenna on the upper deck and attach the receiver to the upper deck or main chassis using silicone sealant or fiber strapping tape. This allows you to remove the receiver box.

Use an AMBrc personal transponder instead of a normal hand-out transponder. Instead of the plastic mount, you can use spare Lexan to mount it to the upper deck (might save a few grams if you don't use too much glue to hold it in place) or use silicone windscreen seal to attach it to the lower deck (next to the lightweight battery pack).

Thank you Frank McKinney

hey pplz
i hav a r40 with the 2004 spec shocks, i was wondering were do the shorter r40 springs go front or rear
thanks

Minus

They're go in the front

MRWRX_69

wen i put on front den my shock shaft only has tiny bit out of the shock
thanks

Minus

I have the same reaction, it's normal, cause when i put the car on the track, the shocks absorbers have good reaction in low or high speed.

MRWRX_69

so its normal

Frank McKinney

Minus - I've edited the lightweight list with part numbers and a couple of other things

Minus

Yes, the shaft must return slightly in the body of the shock absorber, on the other hand the spring must be well in its site in particular the "cup inferior".

Sorry i don't know the exact technical name of the last word.

I saw, many thanks

That $150 is what I said I will have to add onto the R40 to convert the R40 to 2004 spec to race spec, not on the S710.....I want to make a point to say that R40 2004 spec is NOT a brand new car, it is just like a fully loaded R40 with options, just like Mugen MTX3 vs the Pro Spec, or the 705 vs the 710.....and I was using these 2 chassis (including 710) cause they are already OPTIONED.......please don't tell me a Serpent Impulse (with no option) can race national box stock.....S710 is a LOADED and OPTIONED RC car......and can still have more option to add, but they are not required.

Also....to spend $150 on S710 to get even better.........TOO EASY, you can try add up all the lightweight dogbones, hubs, front diff, upgrade rear tower, upgrade front bumper set, pivot balls...............etc...however, I am sure the stock S710 is good enough, but....what is GOOD ENOUGH...? When the sponcered driver beat you with some of the Serpent options, then you will consider those options are the reason that he beat you....

I know, cause I sells plenty of those parts to the local S710 ppl....and everyweek I have to order the exact same parts over and over and over....

Again, please don't think I am putting the S710 or MTX3 ppl down, I know better then that...........and if I have to put someone down, I will pick cars like Traxxx or Tamiya Grasshopper (LOL).........I just can't see myself to spend 2-3X the price on the Serpent parts compare to the AE or HPI parts...........they are dirt cheap, and since, they just break as easy as Serpent, why would i want to spend more money to support a more expensive car when I am running as good with the NTC3 or R40 just like the Impulse or 705 that I used to race.
