how to set up s14 for road racing

[Slappy]

Thanks!

Good luck with that bushing install. I did that on my S13, and it was a HUGE PITA. Not hard, just labor intensive. But I noticed a huge difference immediately after installing them.

Thats what i hear , but with the press and everything we got at the shop it wont be that bad. But there are always gonna be hang ups. Just like when we put that diff in the other night. This one driveshaft bolt took us 20 minutes to get loose.

1) What is the difference between the Energy Suspension ® red and black polyurethane components?

Answer: Both are our Energy's HYPER-FLEX™ performance polyurethane formulations. Energy has impregnated selected black polyurethane components with graphite–to add a lubrication property. Additionally, both Energy Suspension ® red and black polyurethane components are engineered differently than OEM rubber components–to be free a floating and non-binding design. This allows for the additional durometer (firmness) of the components, which adds to the performance improvement of the vehicle overall. Through its 25 years of design and formulation of polyurethane, Energy's polyurethane components are the best on the market today.

Check out the JIC silvia, if it can set lap records against things like the nsx, then their setup must not be to bad

NSX's arnt much to worry about on track, usually for the time attack tuff they have TT some fancy suspension and aero, but no decent drivers.

The JIC silvia is a well developed car (so it seems) with a pro driver most likely can outrun any amature NSX anyday, i know personally i have outrun NSX's already at track events, alot o times the car isnt as fast or the driver isnt as capable and the car makes them seem.

what kind of recomendations do you guys have as far as coilovers? With alot of 240's being geared towards drift it seems stiff coilovers are desirable. Is this the same with roadracing? some of the brands im looking at

SPL KTSSilkroadBuddy clubPart shop maxStance

Thanks!

also the whole large front sway vs stock/none rear sway bar, im assuming this doesnt apply to the rear strut bar? Since it has nothing to do with the wheels?

You dont need coilovers to road race , and "stiff" is hardly ever the best way go. Research for a nice spring/shock combo.

i read earlier in this thread where someone said that you shouldn't get wider tires until you have the experience and the horsepower to put them to use. and i totally agree. however, my build is a little odd.its an 89' coupe with an s14 sr motor, but it is not yet ready to be driven, and is sitting on 1 stock wheel, 1 honda accord wheel, 1 full sized spare and a dounut (tiny).ssoooooo..... i obviously need to upgrade the shoes before i move on to any kind of body/suspension stiffening so i figured i may as well put on the wheels i'll need once it is ready to be driven. right?so i was thinking something like 18x215x40 front and 18x245x40 rear would be good for the kind of setup i will have, as i am not making any plans to go over 300whp any time soon.what do you guys think of this? i just don't want to waste money by going and getting a set of steelies that are going to need to be upgraded in a month (exaggeration)

What are you setting the car up for?

Are the wheels for street tires or R-comps?Are they going to be your DD wheels?18's are HEAVY, Is there a specific tire you want and they only come in the size you need in an 18?

Is this a street car that might see some track time or a track car that might see some street time?

I would probably say go with 16's or 17's. They are usally lighter, which means lower rotating mass and unsprung weight as well as better braking and acceleration. And tires are cheaper as well.

Might try and find some wheels used on the cheap. I bought my "race" wheels for $200.00 for all four, and they had tires on them, they were complety heat cycled out, but they were able to be driven on.

it's a track car and will probably see a fair amount of street before it is completely done. yea, i was thinking 17"s as well, but i want something that is going to look nice too. i'm going for a set of deep dish wheels. and yes, i've been looking for used ones.

Sounds like maybe you need a set of street wheels and a set of race wheels to me.

yes. yes, i think you could be right :\i guess i'll be lookin for a set of steelies after all.

and i'm not gonna lie, i have no track time whatsoever. i got this car as a way for me to start getting into some scca events and eventually TA if i can find any events around here. sooo..... any support/help/whatever would be appreciated Thanks!

[crackler]

Don't feel bad, We all start somewhere. I have only been on a road course once myself. I mainly autoX. I know a lot of road racer / DE guys, and I listen more than I speak.

Before you buy wheels, you need to decide what kind of events you want to run. If you run events with classing rules, IE: anything other that open lapping days/track schools/HPDE's than you need to make sure you don't get the wrong wheels. For instance in autoX if you run STS you are limited to a 7.5" wide wheel, and 205 or 225 (I cant remember off hand, none of the 15's are wider than the allowence, so I have never really worried about it.) tires. Its cheaper to read the rule book first.

If you are just starting out --buy some decent high performance street tires until you get addicted. You will learn more sliding around on street tires than R compounds.

I would have a spare wheel and tire or 2 though.

You might also consider what classes you want to run in AutoX and or Time Attack/time trials --there are limitations depending on what club(s) you run with.

yea i think that would be a good idea.where might i be able to find a "rule book" for time attack, auto x, scca.. all that jazz??

This thread is awesome. I am getting ready to start doing some solo2 events this spring in my s14 and I can't wait!

auto posted some how, weird. . .

hmmmm.. i guess im looking at the modified classexpensive :\ i think it'd be worth it

[sr20goofus]

most people take their car and see what class they fit in or what mods tehy want to do will land them in what class. Why not build a car towards a specific class, maybe using less mods and less money to be in a specific class.

I know personally for roadracing i do not plan to run in the standard ST1 or ST2 classes as an sr powered 240 shoudl be. I plan to stick with the PT classing to the very last point. I just need to keep power down, dont run a huge turbo, no aero, and minimal engine internal modifications. Its a goal that will keep racing competative and relatively cheaper, if i cross into the ST classing i will need to up power by gobs along with HP and weight reduction....a few small mods may screw me over into a much more financially unfriendly class.
