Honda Civic 92-95 advice : add-ons

[mossaidis]

It's nice to know I have a tax rebate coming.... I finished midpack at NHMS and I am looking to upgrade parts before LRP or perhaps 5/9 POC.

1) Tires; I have 2 year old Toyos mounted now - I am thinking SM6, 225/50 Toyo's or 225/45 R6. I would consider the GYs but I can't seem to find prices online (I probably need to call around). Does anyone have prices on new AB special GYs?

2) FD; 4.7, 4.9 or 5.1? I currently have the stock 4.25 FD. Something new from Mfactory would do nice. So, my question is how fast do you ITA boys run at the end of the straights at LRP (before Big bend) and WGI (before the bus stop)?

3) Airdam; I thought a ordered an airdam from Roadracegear.com - but though some oddities including ownership transfers I have not heard anything or gotten anything from those guys. Does anyone have a reputitable airdam fab company that makes an IT legal airdam for EG civic (92-95)? or am I stuck making one out of alum and plaster out of my garage?

Peace,
Mickey

Don't forget Gear-X also for the a 4.7 or 4.9 FD, I can make you a deal on them.

I'm already ahead of you. I am for scheduled 8-9 NARRC events in my first year! Plus I have 25 days on the resume already (it's NOT alot but it's something...) I need PARTS/TIRES for more car potential and NUTS so that I don't slow down when going into the south oval or the carousel at WGI.

this table is very helpfull only thing you have to change is the tire diameter...

That should help you decided on what you want/need.

FYI speed (mph) is a horrible thing to judge your speed with, stock speedo's are off a bunch and then the tires OD makes it even worse. the stock tach isn't any better put most people have an after market tach, which is the best thing to use to judge your speed.

As far as airdamns go this is the best on the market

I have heard good things about Gear-X as well. Need to make a decision on ratio... hmmm. Any guys from the northeast want to charm in on their speeds before the end of the busstop at WGI, the chicane at POC and big bend at LRP?

I believe RRG is back in the hands of Blake Meredith... I believe he sold it and then eventually bought it back. He'll be at RRR this weekend but can be reached here; user id "bamfp". He does a top notch job on everything with really good customer service.

PS
From my experience a 4.7 seems like it's usually the best "all around" gear for most FWD Honda's. I know it worked fine for my EF CRX Si at everything from VIR to CMP to Road Atlanta and even at Daytona.

Limited info I've gotten back, 4.7 vs 4.9 becomes a tradeoff on which corners are in "the wrong gear"....it is a tradeoff.

4.9 Civic/CRX works at ORP and Mid Ohio.

IDEALLY (deep wallet!) you should have both depending on the track and driver. But I'm sure everyone can afford a spare $2000+ tranny just to test a different FD ratio.

[Tom Blaney]

Actually if your motor is working well I have found that the 4.5 gearset is faster since you don't run out of gear in the middle of a corner especially at 2 in L/R or the downhill left at Summit

[Ed Funk]

So, it's really quite easy, you just need one of each!

[mossaidis]

Ed, you are so smart! sounds like a 4.7 is the way to go - redline (7800) in 4th will be about 122. Having a spare tranny is in the plans but until 2010-11.

Jimmyc thank you for the links! Expensive yet it looks like it's worth the money

Xian - no word from Blake on whether he could deliver an airdam - I just had to cancel my check.

There is an easier solution now that IT rules allow cars that have 14" OEM wheel diameters to run 15". I chose a 4.929 final drive (GEAR-X). At small tracks I run my 14" wheels (225/50), while at large tracks (only Road America for me in the Midwest) I run 15" wheels (225/50). With the 15" wheels it is the equivalent of a 4.723 final drive, perfect. This is the B18A engine, so my choice may not be perfect for your application, but the idea is the same.

This did produce some fender clearance issues for me in both the front and rear, but nothing that wasn't resolved with some custom fender rolling.

[jimmyc]

I completly dissagree with Tom B.

Sounds like he is thinking of a d16a6 which is VERY different then the d16z6...

Also there is no "perfect FD", like he claims. Really it is completly track dependant which is why it is important to look at the tracks you run and figure it out from there.

For me 4.9 was amazing and worked great at the two tracks i run at. Plus, another benifit to gearing IMO, is minimizing the gear shifts. This was also accomplish for me with the 4.9.

But i could see at different tracks were the 4.7 would be better..

[downingracing]

Tom B. has a reputation for building VERY good motors. I know he knows what he is talking about. I'm guessing the 4.5 FD comment was meant as the all around best choice for running a single gearbox. I love my 4.9, but have been places where I'd rather have the 4.7 or even my OEM 4.25?... Multiple boxes would be the way to go, but this is club racing and having the 'best' choice for the tracks you run is more like what people have. I run mostly at Mid-Ohio and have found the 4.9 keeps me in 3-4-5 and I'm shifting 1/2 as many times a lap as running the stock FD.

Thanks!
