well im running the ksport setup on my crx, and the spring rates arent great wich leads me to belive why i am not all that great in my 60' area

so new setup will be tuned at 600, and probly be ran mostly at 550 so i was thinking 10k front 8k rear what do you guys think would be the best spring rates to put on my ksports to the best possible 60'

 

im runnig k sports with no problems 1.6 60ft car runs 10s

 

yeah i ran 10's aready but i have a unloadin problem so i was asking for insight and im glad youve ran 10's with yours man and im not meaning to come across as disrespectfull either.

watch and youll see what im saying car noses big time from unloading

what spring do you have in the rear?

 

i was just actually out looking and i have

f=10k
rear=6k

 

6k rear? that is way to soft of a spring for what you are doing, I run a 18k spring in the rear and 12k up front.

 

well i am running what came with the coil overs lol and ima get some skunk 2 springs to slap on so im trying to get opinions.

but i just looked at some logs and going from 7200-3500 at launch isnt good either that could mess with the 60's

 

i was running 10ks b4 and my car was way in the air,i was just saying that on mine i luv em

 

how much boost are u building off the line?

 

log looks like this in 2 step

engine load 6.76
boost target 9.9
engine speed 7520

 

Sounds like its bogging pretty bad...i got some old *** bg coilovers on my **** i have no idea what the rates are but it used to come out like urs..i raised my **** up more all the way around it helped alot! I think the bogging is whats hurtin u the most try raising it up too..i get 1.61s on mine allday with open diff and stock axles

 

me and the tuner spent a day at the track, and we raised lowered did this and that and nothing seemed to work for us.

went from soft cut to medium/ medium did yeild a better result though.

 

Sanman are your front springs preloaded at all? i did that to mine to keep it from nosing down.

 

i could have sworn i replied

i need an explanation of preloaded

 

Pmed you

 

I dont think changing your rears from 6k to 8k is going to do anything...

Is this a track only car or do you drive on the street frequently as well? If track only go to 16k or 18k...that will help your car from squatting on the line.
