*ZIP file

very easy to use.. just measure ur car power at 400m..check ur top speed at 400m mark then adjust a bit..make sure ur car at the finish line at gear 5 at top rpm (max hp rpm)

arent drag racing runs diffrerent ratios from track racing?

you have to estimate the terrain as well, as for example:

after corner got uphill? downhill? sweepers? long corners? chicane?

yeah la hp is the max factor but for track racing torque plays a very important part too...

as for hondas i got the specs, but sorry ah...trade secret. generally for a guideline, a longer final drive ratio from an aftermarket product is needed in sepang due to it's long straights. you figure the rest.

top speed can be alter by changing the combination of 5th (if this is top gear) gear ratio and final drive ratio. if u put 1-5 ratio to close ratio but final drive has lesser figure (smaller number), ur top speed will still be the same or higher

Hi all,

I'm looking for new set of absorbers & spring for my 2004 Kia Spectra. I understand that RS-One sells GAB suspension (HA series) for my Spectra.

Also found out that Hotbits has suspension of my car too.

Need advice. Based on your experience, which would you recommend ? Hotbits or GAB?

Thanks in advance....
