The FL5 Civic Type R Wheel Spacer Reference Thread

[Clark_Kent]

With 15F & 18R, do you see any diminish driving response or sharpness (compared to pre-spacer) ?

On the street, I have not experienced/noticed compromised steering response as a result of the spacers. If there is a difference, it's indistinguishable to me.

Do you have to check the torque every few months or so?

No.

No.

Just the 50-100mi post install re-torque?

Correct. That's what they suggest; however, it's doubtful very many people do it.

Wow. Not good. Should be checked/re-torqued 50-100mi after install and then every few thousand miles. Otherwise could be trouble, which is why spacers get a bad rep.

Having a hard time between the 15mm and the 20mm variants, any reccomendations if I plan on keeping the stock suspension?

It depends on the look you're going for. Flush with the fenders or something more aggressive? There are also differing opinions on the size that will give you the flush with the fenders appearance. I suggest looking at the photos posted in this thread to gauge the various options.

That is correct - the stock studs on the oem hub remains, the spacer is secured to these studs using the supplied low profile nuts. The wheel is then positioned over the studs attached to the spacer and secured using the OEM wheel nuts. The correct spacer is the one above - which is commonly referred to as a "bolt-on" spacer.

The spacer below (which is what I suspect you have tried to fit) is considered a "slip-on" spacer and will not work with the oem studs - the oem studs will need to be removed and extended ones fitted (the extension of which needs to match the thickness of the spacer). Additionally, the extended studs need to be M14x1.5 matching the OEM thread diameter and pitch.

Do you know if I would need extended studs for 5mm slip on spacers? Autocross rules state no more than 7mm from stock offset

I am installing some this weekend and can let you know. I am not too worried, but am only installing them in the back. You can always go 3mm if you are concerned as those will definitely work.

 

[ZeroGSR]

As an update, added the 5mm slip on spacers in the back, got plenty of engagement on the lugs, but I am NOT on OEM wheels or nuts for what it's worth.

One note, don't buy the cheap ones off Amazon. I got the Akatas and they seem pretty well made for what they are, fit fine.

Just got the bonoss spacers I never ran spacers in general so I don’t really have any experience with them. Are the torque specs the same as the wheels at 94ft pounds? What intervals (miles) do I re torque them at?
