Touge Tuning Guide *Updated!*

Remember tho wha works for some doesnt work for others and i am by no means an expert tuner. Hope the info helped my g

With a lets say 2000 lb car i wud set my spring rates between 420 and 350 in the front and 310 to 375 in the rear. The heavier the car the stiffer i make my springs the lighter the car the softer the springs

That's working or me to, I just started doing that

a simple way to set your spring rates to start tuning from is like this:

weight divided by 2

multiply by weight distribution for front springs

weight divided by 2 then subtract the front spring rate to get your rear springs

example-

2478 lbs. car with a 53% weight distribution

2478/2 = 1239

1239 x .53 = 656.67

1239 - 656.67 = 582.33


so front springs 657 rear springs 582

may seem a little stiff for some but its a good place to start tuning the balance. not to mention on the touge its soft dampers, not springs, that matter, IMO.

Or just install sport springs lmao. Works better IMO

It will never be better, that's just lazy

If it's lazy and it works then who cares right? None of my cars have race springs.

I've never had a race suspension setup that felt right. Sport suspension is a little too soft but I prefer it and make faster times with it so I stick to it.

Not saying it doesn't work, I can't dispute that. But race springs will always have more potential. If you took the time you could set race springs to feel excatly like sport does, while still being able to fine tune it. Even if sport springs feel good they'll never be perfect. No setup will ever be pefect, but race springs will get you closer. Kraze I bet you'd hit that 4'30 if you took the time to really tune your suspension well.

THX, for the help!

As far as suspension goes, I used the calculations that some one else posted (I forget who, so I apologize). The formula may seem weird, but It feels very balanced. Instead of tryin to explain it I'll just show you an example.
--Okay, as an example I will use a tune from a 300ZX if I'm not minstaken.
It weighs 2765 with 52% front distribution, those are the only variables you need is weight and dist.

2765 x 0.75 = 2073.75
2073.75 x 0.25 = 518.4375
2073.75 - 518.4375 = 1555.3125
1555.3125 x 0.52 = 808.7625 Front
1555.3125 x 0.48 = 746.55 Rear

I guess the formula wouldnt be THAT hard to explain, eh? But it's very easy and every single time I've done this several times with several different cars and the cars always feel extremely well balanced. I actually almost broke the 40's in my 240SX. I got a 40.1 NDH =]

If you're taking .75 and then .75 of the result why not just multiply by .5625 initially instead of bothering with all that extra math at the beginning.

it's x .75 then - .25 of the result.

Is it bad that when I tuned my car following this guide I'm now slower than when the car just had the upgrades and no tune

No, because as a beginner tuning your car almost always makes it even harder to race. Even once you're at a high level, tuning has to be done very carefully or you risk throwing the whole car's balance off.

I may try tuning it the way I would for circuit racing and see if it feels better. Maybe it's just that I like my car to be a cirtain way that the setup didn't give me
