race/track car
 

doing some research for my build and i need some help. my car will be a track only race car. but i need help with a few parts, i come from the nissan world and this car is built way different.

i need help with SOLID SWAYS and REAR CAMBER

again this will be a track only car. opinions and thoughts are needed

Need more information. What is your suspension set up now and do you have any planned mods? And what tires?

- Andrew

whiteline sways
whiteline rear camber bushes
lca's from several vendors

right now all stock

will go with kw v3 coils, vorshlag front camber. ill be running enekis (17s) with RS3 tires. most likely AP racing brakes. gt spec bars all around.

is whiteline solid?

whiteline Rear Sway bar - 16mm heavy duty blade adjustabl
whiteline Front Sway bar - 22mm heavy dut
Kw v3
vorschlang camber plates
cusco rear lower control arms
whiteline for front control arms bushings, rear subframe, differential, transmission mount.
perrin engine mounts.
ap racing sprint brakes
thats my setup, I could use some help with the tuning regarding sway bar, shocks and alignment settings, and your setup looks identical to mine

whiteline sway bars are solids

i would recommend deciding not to make a track only car until you know what you want. things like street tires and strut bars are kinda wasted on a track car. the best thing to do in search of a track car would be to just buy a spec miata for a fraction of the price.

What's your long term plan? What's your budget?

long term plan is trailer only race car. life long budget lol i want quality. i want the best. things like trunk struts im not looking into. my car will be caged.

ive been racing cars for a long time now, i know how a car should behave on a track and under extreme conditions. i just need to know the corrrect adjustable parts so i can adjust after each track session.

What parts do you want to adjust? Check in to cortex they have some pretty awesome looking suspension parts.

would the bigger front and rear sways cause too much under/oversteer? i mean it is adjustable. so y not have it just for the drift days (i perfer to grip n go instead of drifting). also isnt the gtspec rear camber arms better built?

camber/caster, sways, coils

Yeah check out cortex they have some front lower control arms you would be interested in. For sways I'm a big whiteline fan and they also have some rear lower control arms coming out soon.
Tein src coilovers (highly recommended by CSG)
Cortex front LCA
Whiteline rear LCA
Whiteline front and rear adjustable sways
Ap racing endurance bbk
Should be a good start for a track car from what I have seen.

What's the short term plan? Budget for now?

W2W? Time attack? Weekend track car? Classing? Restrictions?

Weight and power goals?

What is your driving experience? What classes have you raced? What cars have you previously driven? What mods? How do you want the car to behave?

The more information you provide me, the more I can provide for you. I don't like recommending parts for the short term that are eventually going to get replaced in the long term, and I can make recommendations for any budget, but I gotta know what your eventual goal is to do so.

short term is DD and weekend track car. ive done time attack mostly, few drift event but mehh i like grip and laptimes more. i enjoy doing hot laps, getting the fastest times possible. weight is as low as possible, power for this car i want 280-320whp. ive been racing starting with karts since i was 13. my frist and second track car was both a 350z (ive had 2). ive always signed up in the super advanced class. ive had a few power mods but mainly was chasis/handling/braking/r-compounds. thats all i need, but this car is way underpowered. i dont believe in doin work twice, if imma get a mod, i will save up and get the correct mod the first time, not go back and change things, only things i would change is adjustments.

Race car, eh? What series and what class. Rules often dictate what can and can't be done.

Damn those arms are nice. I never heard of them, thanks for posting this.

You might be interested in our upcoming RCE Tarmac 2 coilovers. Built by KW to our specs, they're more of a "clubsport" set-up than standard V3s.

We've been testing them with the Whiteline 20mm front and 16mm rear solid swaybars with excellent results on street tires.

- Andrew

those coils look good, any specs on them? reason why im leaning towards KW is because i can get wholesale from them lol. building a race car is not cheap my friend lol

Precisely why I keep asking what your budget is.

You say you're in the 818?

What's been done to your Z, and what lap times do you run at our local tracks?

What is your goal in terms of lap times?

Also, please try to answer EVERY question I previously asked. The more information you provide me, the better recommendations I can give you. Our shop car currently holds all the local NA/street tire records, with a VERY simple setup.

Rims, RS3, Suspension, axleback. Nothing else; no intake, no arms, no bushings, no sways, no gutting, nothing. As we've both stated, it's about quality, not price, and you gotta pay to play.

Mike will definitely steer you in the right direction, no need buying parts you don't need it's amazing what they have done without even adding any power. I would copy their setup to start and maybe add some power via tuning and intake and exhaust. I'm not tracking mine but if I was I would definitely have them install and set it up if I was that close.

there is no budget. just time. i dont care what quality parts cost, im not gonna buy everything at once, every mod has its time frame.

my z mods: no motor mods, coils/sways/arms, rims/rs3's, bucket/5point, oem brembos but track rotors/pads/lines. i had simple mods. i ran all willow spring tracks. my home is streets of willow though. i was in the 1:26's at streets (both directions).

your knowledge is more then welcome. and if i miss a question im not avoiding it. lol

thank you guys for your help!!!

No budget? Save, and buy a faster car. Seriously.

I'd love to have an unlimited budget.... a 458 challenge would be nice.

as much as i would love a gt3rs, this is my track toy lol
im saving for mods, however long it takes me to finish this car. but in the mean time it will be tracked and enjoyed.

RCE, Matt Andrews and CSGMike seem to have nailed the basic formula for you - wider wheels, better rubber, high end coilovers, BBK and geometry correction/camber plates.

Beyond that I suggest you do a search for what Robispec is up to as far as geometrically correct front control arms etc.

Oh, and the weight savings part could be interesting too given that it's gonna be a track only machine. Stripped out, lightweight battery & exhaust, etc.
