i recently purchased a 03 accord 2.4L 2dr and i want to set up the car for serious handling. basically i'm looking to increase the lateral g's of which my car can handle. i have been doing some research and i found that my car handles around .85 and the S2000 is around .89 and the new Viper is 1.04. so i'm looking to create the perfect formula. i think i need a strut tower brace, wheels, tires, and suspension. i don't know who makes what type of suspension but i found Tein sells some and i don't know what tire and wheel size is right, maybe stock is fine or wider? i have no clue. hopefully what i wrote makes sense to someone. if any of my info is incorrect please let me know.

The perfect formula, eh?
Hmm- time for another overly-elaborate answer!
Okay- perfect for what?
For street, you'll want some compliance. Stick to poly (polyurethane, that is!) bushings, to allow SOME deflection (you'll want that when you hit potholes, small children, lizards, etc.), DOT rated tires with at LEAST 80 treadwear rating (most R-compounds die young), and springs and dampers with some travel and, again, compliance, and a chassis with a little give in it (to keep your fillings in place).
If you're going balls-to-the-wall race (which I doubt- no offense!), get rid of all the above- go solid metal mounts and bushings, Hoosier slicks (who likes getting more than a thousand miles per pair anyway?), the stiffest stuff you can find, a 12-point cage, and lots of weight reduction and spot welding. No? I thought not :)

Here's my perfect plan:
Eibach Sportline (more lower, but more stiffer- they're still pretty streetable) springs- $211- Tirerack
Koni Sport shocks/struts (good, adjustable, yellow)- $616- Tirerack (guess where I'm looking!)
Eibach front camber kit (dial it in right, keep the car out of the alignment shop every other week)- $151- Tirerack
Ingalls rear camber kit (see above!)- $77- Tirerack
Progress rear sway/tie bar kit (less craptastic understeer, and a bit of bling)- $159 shipped- Corsport (one of the site's pimpinest sponsors- go Tai!)
Greddy front strut tower bar (more stiffness=mo'better! )- $130 shipped- Corsport

That would be a VERY good place to start. Wheels, of course, are a matter of opinion and personal style. Here are some FACTS, however:
18" is the ABSOLUTE MAXIMUM for function vs. style. I don't give a rat's left testicle if Porsaginirari or whomever goes bigger: IT'S JUST FOR LOOKS! That is where the cutoff is for bling vs. true engineering lays. Period. Stick to 7" width or less, please. Chrome is a waste of $- it holds in heat, requires maintenance, and looks dumb on a Honda. Also, try to get a set of lighter wheels if you REALLY care about handling- lighter=BETTER! Less unsprung weight (wheels, tires, brakes, etc.)= BETTER HANDLING! Up to a point, of course, but it's a pretty solid rule.
Wider than 225 (maybe 235) for any Honda is pushing it, ESPECIALLY for a street car. 225/45/17 is a great size- it'll fit, it's common as hell for a lot of brands, and it'll give you the low-profile look, AND better tire choices.
For tires, if you have deep pockets, rock Toyo RA-1's. They get decent tread wear (I've put 8k+ on them with track time), ride decent, and can be run in the rain (they're used for rain races, actually). They're available in a decent number of sizes, and pretty affordable. They don't need heat cycling, can be flipped inside out, and many tire stores can special order them for a decent price.
For a more affordable tire, Yokohama EVS 1000's are pretty good, and Kumho Ecsta's are an undeniable value. Stay away from cheap shit tires (Hankook!!!)- tires stop your car, and are the KEY link in your car's handling.
If you get all this, and still want more, give me a holler- there's plenty of room left to improve on the above formula :)
Cheers, again- Mark W.

Hah- nah, just a major dork who's spent way too much time in R&D for his racetoy :)

I'm not sure if the Stage II would, but the Stage I should fit any Gen 7 Accord.

is there a limited slip differential available for the 7th gen accords?

Any limited slip for the K-series transmission SHOULD fit the Accord tranny- I have a Mugen piece for sale if you're interested... :) Mark W.

how much are u asking?

Asking $1,200
They go for $1,680 brand new from King. I just passed the return date, and with shipping and all, that's about what I'd get from them- I'd rather just hook somebody else up with a sick deal- Mark W.

are there any differences between that and a quaife lsd.

thaduke2003

Quaife will lose grip if one tire is in snow/mud/goo (ask me how I know!), this won't. It's a much more street-able diff, and won't throw off your steering or cause as much torque-steer. It'll give you about the same increase in turning radius, however.
This is more like the OEM LSD in the new Civic Si, but designed to handle a buttload more power. King told me they've NEVER seen one break, and they use them in their own vehicles. Either diff is very good, but the Mugen is made by guys who JUST do Honda, all day long, instead of any car they can profit from.
Call King and get the lowdown from them- those guys can choose for their own car between Quaife and Mugen (they sell both) and they use Mugen, so that (and the usual multi-month wait for Quaife's bits) sold me on this. Sadly, however, my car got stripped by assholes, so I have no use for it- Mark W.

well, im definately interested, i just dont know when i can afford it. I just bought the tein super street coilovers so my bank account is hurtin. in a month or so i will be ready to buy if you still have it. also is this a difficult install?

Well, you'd want to pull the tranny, pull that apart, and replace your bearings with it- it's a day or two of straight work, but well worth it- Mark W.

also, i see that you work on cars for a living, is it possible to hire you to help with the install?

I'm afraid I already have a solid schedule for the next 2 months- race season! Yaay? Money's good, hours (120 a week) suck balls- I'm around if you need help, however- Mark W.

this install is over my head so if i can find someone to do the work for a fair price then ill get the part from you. thanks

Sure- no problem man- it's all shiny and new, and making me sad to have to sell it, but like I said, I'd rather hook someone up than have someone else pay full price for it- Mark W.

well its time for new tires, so does anyone have any suggestions on a better tire size for my stock rims that would provide better performance. the original tires are 205/60-16. i do drive like a maniac if that gives a description of how they will be used.

thaduke2003
09-01-2008, 06:45 PM
On stock rims, you NEVER want to go more than 10mm wider, if even that. 6.5" rims can fit a max of 215 SAFELY- sure, there are dudes running 225's, but they're idiots asking to rip a tire off a rim. By that count, 215/55/16's should fit nicely if you're on 16X6.5" wheels- Mark W.
