kosei k1 redrill lug hole good idea or bad?

[ismaelae86]

i cant seem to find any kosei wheels that are 5x114 so would it be a bad idea to buysome used 4x114 and redrill them to 5x114....thanks for your time

If you can find a machine shop that will do it to the same kind of tolerances the factory holds, it seems like it would be fine. How you know everything is right is a great question, of course...

94-99 V6 Mustang wheels, 3 spoke which is great for brake cooling, 13 lbs, 15x7 with a perfect 24mm offset, 100-200 for 4 all of the time.

wow really 13lbs?? really hmmmm interesting

If Mustang wheels don't work out....

Redrilling a 4 lug wheel to 5 lug usually requires some welding/filling, especially when the bolt circle is the same. I would think you'd be better off redrilling a 5 lug wheel such that it would end up having 10 holes equally spaced, 5 on each circle.

I have a set or two of Kosei wheels that came off my RX-7, I will post some pictures and price if you are interested ?

[ismaelae86]

yeah for sure let me know the ony thing that will kill me is the shipping but if the price it right why not let me know...

i actually found a set of 5x100 for 250 that ijust bought from somebody that i will redrill but imma still be looking for a few more sets

You'll need a good size spacer since they are +48 but at least they are the correct bolt pattern.

nice find thanks

When you talk about redrilling these, you are planning on welding up the original holes, right?

Because otherwise I think this is a really bad idea.

[Spinnetti]

no need to weld up the old holes, but doncha need some hardened steel seat to press into the new holes? I've redrilled wheels before. Its no biggie, but can't just seat them in soft aluminum - they will wear out.

[ismaelae86]

well im not sure exactly how its going to get done im guessing that they will weld up the holes, i just got pointed towards a shop by my friends that get there wheels redrilled....they have been going to this places for years and they do good work

[lawtonglenn]

It is quite common in aftermarket wheels to be
predrilled for two bolt patterns, so there is no need
to plug up the original 5x120 or 5x100 pattern when
putting in a new 5x114 pattern.

Recently I got some inexpensive 6.5 wides for the
Hoosier wets (since they only come in 205 not 225).
Here is a closeup pic showing all 10 holes.

We use Koseis for our race tires, but for the wets
I'm betting the 6.5 will be fine. Only $74 at DTD in
15x6.5 38ET (5x100 and 5x114). I will weigh them if
anyone is interested.

[ismaelae86]

im interested in its weight

[lawtonglenn]

The $74 MB wheels weigh 15.2 lbs each...just weighed one.

[ismaelae86]

not bad at all for the price...thats good thanks for the info

[ismaelae86]

just wondering how much should a kosei with toyo ra-1 weigh?

[Eagle7]

IIRC, the K1 is 13.2 lbs. Don't know what a Toyo runs - I think my Hoosier 225-45-15's are about 20 lbs.

[ismaelae86]

r compounds are pretty heavy arent they?

[Eagle7]

Nope, Tire rack has the Hoosier at 19 lbs. The only street tire in that size is 21 lbs.
