19s for autox and road race

[kdrkmstp]

Are 19s too big for autox and road racing?
Also could 235/35/19s fit on our 2g cars, if so
with what offset. I read that it could fit with
+40 offset and someone else also said it
rubs in the back and etc. Let me know if
anyone is running 235/35/19s on their 2g.

How big of a brake do you plan on running that has you requiring running 19" rims?

The Ferrari Enzo has 19s so I think you should be ok.

 

[kdrkmstp]

Is not because I have huge breaks, its just that
I wanna make it look good for show and be able to race with it.

19's are way too big, get the smallest wheel that will fit over your brakes and run a dedicated racing tire like Kumho Ecsta V700, Toyo Proxes RA-1, or even the Hoo$ier$. Swap on the race wheels/tires at the event, your performance will be much much better.

And when I drive a DSM, it's just like driving a Ferrari. GMFB.

There's no excuse for 19s. 18s are plenty to clear even the best brake kits.

Yup. That's me.

Come on over and ask.

 

[eMKay]

Well, only 2 questions right now

What would you suggest for spring rates for coilovers? For road racing (also autocross)

Do you know of anyone that needs to get rid of a 420a engine?

my gf has no prob handling her car on 19's with eibach sportlines/tokico blues. 19x7.5 with 225/45. handles great up to 135mph so far, havent gotten above that yet

No one is saying 19s will make a car undrivable. The question was: "Are 19s too big for autox and road racing?." The answer is yes, they are to big because your car will be slower with them as compared to 17s or 16s. If you desire the looks of a 19" wheel but also want to autocross or road race then you might consider a compromise, such as 17s.

Depends on 2 things:

1) How much you are willing to spend
2) How much you want to sacrifice.

You probably don't want the rates I run in my AWD (650/550) for a few different reasons. It really depends on your driving style.

 

[eMKay]

Well, for #1 that's not really an issue since springs for coilovers are pretty inexpensive ($50 or so each).

I'm not sure what you mean by sacrifice, this car will not be driven on the street, and it will have a cage installed making the body much stiffer, so I can go as stiff as I want, your rates are about what I was thinking, maybe a little softer in the rear. I want to tune this car for road racing first, then autocross.

2 things that are going to make yours react different than mine. FWD vs AWD and weight distribution. As far as figuring out a good ratio starting point (front to rear), almost any heavy FWD ratio will work. Then bump up the fronts.

I would think a 600-700 front with a softer rear (maybe 400) and add a heavy rear sway to preload the rear. Make sure you invest it damn good shocks. Springs are just twisted metal but a great shock is worth its weight in gold.

higher front spring rate will increase understeer. you want a higher rate in the rear to rotate the car, regardless of the sway bar.

19's are way to big to be compeditive. its not the weight so much that will effect it in autox, but the small tires. the extremely small sidewalls is what will hurt you the most. touring cars only run huge wheels to fit big ass brakes in there.

yea u guys are right about the 19's, i was just sayin,

btw not to change topic, but tevenor are you in nyccdsm.com ????

Yeah, that's why I was thinking of going a little softer in the rear than you, my car will be much lighter and being FWD will not tend to push as much, I plan on either running Koni's or Illumina's and a nice stiff bar, from what I hear the stock front bar is pretty stiff, is that true? Or is that just for the AWD models?

Why would this even be considered a good comparison .

Why not? Cars all work the same.

Please tell me that, at some point, you'll get tired of making a fool of yourself.
