The Choices..... Build Up Questions

[Rixsy]

I say brakes, cos they're cool for stopping and it's fun

[macoman69]

yeah but i cant get brakes without wheels anyway lol

[air23box]

Wheels +1 again....as most of them explain clearly already.....I personally wouldn't go any aftermarket wheels......just for safty reason......life is something $$ can't buy.....so I prefer pay more for better quality parts.....

[l3vnd1]

I love my stock smoked 15inch wheels.

[00dc2]

they do me fine for my purposes...

but i praise my forged Racing Hart CP-035's at every event i race at...

why are they such a benefit?

[phat_nam]

wheels + 1, why not some ce28's? i reckon they look better than re30's..

[macoman69]

CE28's dont suit CW DC2R

[tinkerbell]

why are they such a benefit?

Lower "unsprung weight"

The phrase goes:

"Weight is the enemy, unsprung weight is the devil..."

So a lighter wheel (mine are 3.9kg) will react more quickly to changes in direction, will be easier to follow the contours of the road and will place less stress on the shock absorber assembly... thus improving lap times and consistency...

There is a bit here: http://en.wikipedia.org/wiki/Unsprung_weight

And here is a quite emotionaly charged quote from a (biased) part shop website here:

“Unsprung weight is the nemesis of the suspension in the war to maintain tire contact with the tarmac.”

plus - as i change my rims at the track, going from cast alloy 16's to forged alloy JDM 15's - i can feel immediately the change in performance.

wheels for sure,
I think the rule of thumb is
for every 1Kg you take out of your unsprung weight
equals to about 4-5Kg of weight reduction elsewhere

Lower "unsprung weight"

i know the concept. i just didnt think the effect would be so pronounced that you would notice it so much on the track

so you must have the 15x6.5 CP035R's.. nice. my problem with them was color.. no gunmetal to match my cars black.

i have SSR TypeC's in 16x7 they are 5kg Vs 5.9 for stock. yours at 3.9 are VERY light!

You know spoon calipers are apparently over 1kg lighter than stock DC2R calipers? have you got them?

[RichyR]

CE28's dont suit CW DC2R

Yeah they don't

Rims + 1

[tinkerbell]

abotu 1.5kg or 2.8kg depending on whether the spoon site is referring to 2 or 1 calipers:



no, i do not have these

but as i already said above regarding the DC2R ones;

they do me fine for my purposes...

[macoman69]

Yeah they don't

Rims + 1

Lol!
Ok i stand corrected.

But i still think i would prefer the RE30's

what do you guys think RE30's yay or nay?

[felixR]

yay for RE30

+1 again for Rims.. and please.. no Rotas (or Nangkangs)!!!
