What is the widest wheel setup I can run w/Enkei RPF1?

I will eventually hit 300hp with a built B20v motor and traction will be my biggest bottleneck.

I don't really want to run wheel spacers (I think they look cheesy and they mess with suspension geometry) but that is a last resort.

If I have to - I will do an Integra 5-lug conversion with appropriate hardware as part of my brake upgrades.

I like the look of Enkei RPF1 (mainly that they are 9.5lbs/rim)

I cannot find RPF1 rims wider than 7inches in 4x100mm (CRX/Civic) lug pattern.

I am looking to run 15inch or 16inch rims (only want to run 16inch if I HAVE TO for the big brakes to clear.)

I have 2 RPF1 rims already (7inch wide) -- I can use those for the rears (possibly space them out to match wider front rims if I have to)

Thanks for the shouts!

 

I forsee disaster.

 

lol

 

thanks for the advice guys!

 

you can indeed find these in 16x8 4x100

 

You should hit 300 no problem with nitrous. as for spacing some 20mm fenders will give you a lot of room.

 

What did you expect? You say what you want to do and then list everything you DON'T want to do which pretty much NEGATES everything you would need to do to accomplish your objective.

Apparently 15inch RPF1 are only made up to 7inch wide.

as pwebb said... If i bump up to 16inch RPF1 they are made 8inch wide. Also available in 4x100. Thanks dude! (38mm offset)

If I want 8.5inch wide, I'll need a 5-lug conversion. And I'm stuck with 17inch rims.

If I can handle 17inch rims without rubbing, and I'm going to the trouble of a 5-lug conversion, I can buy 10inch wide RPF1 with 5x114.3mm bolt pattern (and 38mm offset.)

And if I want 10.5inch wide RPF1 (biggest size they are made in) I will have to fit 18inch rims (probably not possible without welding a lift kit.) - 18x10.5 @ 5 lug x 114.3mm (15mm offset) ---- Probably not possible. Even just for the fronts..

So now my question is: Is 5x114.3mm bolt pattern (and 38mm offset) a Honda bolt pattern? Integra? Anyone know what year?

thanks so much guys. it feels like it's been years leading up to this build cuz it has :D

 

Integra Type-R (any except the 96-spec)
NSX
RSX
Accord (not all years)
Legend (not all years)
CL
the list goes on to include nearly every 5 bolt Honda/Acura...

 

Here is a list of a few Honda vehicles in production with the 5x114.3mm bolt pattern. Offset on the following vehicles varies from model/year to model/year.

97-02 Prelude
02-09 Pilot
95-04 Odyssey
03-11 Element
97-11 CRV
06-11 Civic
03-11 Accord
98-02 Accord V6

Does anyone have any information on a documented retrofit to an older generation Civic? How can I get this bolt pattern (5x114.3mm) - found on the aforementioned Hondas - onto an older generation civic? Has it been done?

 

Dude you are the f^cking man. I need to know where you got the information from this 'list.'

So far my research hasn't turned up much..

Thanks so much HT

 

I suggest you read on here how to complete this task. Wider rims do not mean grip. Grip is composed of a good compound tire with a specific PSI and a certain temperature, along with a great suspension setup and a great transmission. You specified 300hp which there are a ton on here who have completed that and ran a 15 x 7 rim with not an issue. You have to take in to account the curb weight of the vehicle as well and what that will be when complete. I would start with suspension then move on to tires.

 

thanks for the reply.

-Suspension is Koni Yellow struts with adjustable/perch/ride height ground control coilovers with custom tuned spring rate for the weight of the car.
-Sway bars are tuned to the proper torsion based on the vehicle weight as well.
-Full poly urethane bushings are used in place of all soft OEM rubber (except the notorious rear trailing arm, which is softer than urethane - Mugen hard rubber - higher durometer than oem rubber.)
-Balljoints/tie rods/etc are all new oem honda.
-Transmission is integra type-R with quaife limited slip differential.
-Tire compound is currently undecided as i have not done any testing. (sticky and soft though I'm guessing for test #1)
-Tire PSI is also undecided, but i'll start my testing with 32psi front/28psi rear.
-There are also numerous chassis braces, traction bars, and tie-bars/strut tower bars.

The only thing left in the equation (that I can think of) is the contact patch of the tire. In this case (as far as I know) ---- the bigger the better.

The more tire contact to the road, the more traction. Unless I'm mistaken.

Does anyone have any information on a documented retrofit to an older generation Civic? How can I get this bolt pattern (5x114.3mm) - found on the aforementioned Hondas - onto an older generation civic? Has it been done?

Thanks much to all participating!

 

Oh and I'm expecting the curb weight of the vehicle to come in at 2100lbs. (Give or take)

Curb weight oem is 2060lb, as stated on my pinkslip. I have the weight reduction planned to remove quite a few lbs, and add it back as my bodyweight.

and this is my 1000th post Wooo HOOO!!

 

The easiest solution is CRV or ITR, in terms of making your car into a 5x114.3 bolt pattern. With the ITR as the donor, you also get the larger brakes (though they're a detriment for a drag car).

And some logic is finally brought into the thread, though I always preach tires as the most important item (over suspension).

 

I hate to feel like i'm asking the same old questions again buuuuut - what year/model of ITR will I need parts from, and will it be a direct swap onto CRX or will I need mods?

Thanks dude

 

CRX? Where'd that come from?

You could also have the wheels re-barled, but, you really need is a set of good sticky tires.

 

CRX isn't purchased yet. Bought one and it was too far gone, so sold it. Going on car buying mission this month to buy a mint one.

I know this 'Put X brakes on CRX' issue is well documented, but this is still a pain in the @ss.

Does anyone know how 95-98 Honda Odyssey brakes would bold up? Because I have a totalled odyssey sitting in my back yard - and they do have 11.1" front disc. And they do have 5x114.3mm hubs on them. And I have a whole totalled odyssed (just cosmetic damage) sitting in my back yard. A whole one, with a whole set of control arms, brakes, hubs, all of it..... just sitting. in my back yard. totalled.

 

where is it sitting again because i dont think i cought it and also what condition is it brand new???.....

 

I believe that the hubs, brake brackets, calipers, and rotors are needed, but you might also need new bearings and axles depending on where you source the donor parts.

Search around, it is well documented, but it isn't something that I know too much about since I've never felt the need to change lug patterns.

 

Thanks researching this lug conversion/brake upgrade will be my number 1 priority for today until later.

From the order the parts come off the car [wheels 5x114.3mm>calipers>rotors>hub>wheelbearing>knuckle s(because its pressed into bearing/hub)]

thanks guys..

bump for any info on Odyssey part interchangeability - they are 11.1" disc fnt/rr (with different sized calipers to proportion) and 5x114.3mm lug pattern....

 

what about a 16x8 rpf set,on a del sol, will that fits ok????
need some opinions!!

 

Pick tires first.

Then you can decide on wheels.

15" is what I'd recommend.

Vertical contact is most important for straight line traction.

You can find tons of 4lug wheels on 15" and widths up to 15" for ~$100 each.

 

Old thread. And this was for a CRX so I don't know why it's in here.

 

Well i dont want to pick the tires first,because i have a 305mm brake rotors at front.thats the reason i want to go 16 inches.Also straight line is not for my car,i am going for a time attack setup,so might have 2,5 degrees of negative camber...anyway i prefer the rpf wheels becouse of them weight and i will try for 225 or a 235 semi slick tire.So i think that the perfect size would be 16x8.This im not sure about is the offset.Help!!!
