Archives..no luck. Anyone know if Ronal Firehawk rims will clear the C5 uprgrade? Thanks!

bump to top, im trying to find out the same thing...

I highly doubt it. Between the size of the calipers and the offset of the rotors it's not likely although I could be wrong. I'd try and find some high offset rotors. If you've got some dimensions of the ronal wheels I could tell you for sure since I've already modeled the brakes in solidworks.

Im hoping to pick up a set of firehawk rim swith in the next few weeks. and could mock em up and see.

I hope they fit or I'll be mad..

what would you like, inside diameter and backspacing? i could do it tomorrow or thiis weekend...

Just by looking at the rims, I'd say no, they wont fit. But I havent gotten a caliper to test it with yet. The problem with firehawk rims that they taper in as you move towards the face of the rim. The Baer 13" kit will fit with some minor caliper grinding I'm told. But they sit farther away from the face of the rim then the C5 brakes.

i think this has been asked before and im 95% sure that they dont fit , These firehawk wheels have a lot of fitament problems with large brakes .

I'd need as many measurements possible. A cross section would be ideal but the inside is really all that matters.

what about 1LE do they fit?

Justins86bird

Fit like a glove. Lots of room and dont need spacers.

JPrevost

The 1Le's use the thin PBR caliper and a rotor with good offset. Plenty of room for them, probably enough room for LS1 rotors and the newer calipers. Just need to use a high offset rotor .

The 91/92 Firehawks had the option for the 13" Brembo brakes and they cleared the wheels, the C5 brakes are only 12.8, right?

I know the Baer Track kit for the 3rd gens fit the Ronals just fine since that is what my friend has on his 82 Trans Am.

JPrevost

That kit uses the thiner PBR caliper and I'm not sure about the rotor offset but isn't the track kit a c4 HD rotor? That would explain them fitting.
Anybody have the dimensions of the inside of a ronal wheel? If so, please send them and I'll model it for clearance issues.

Justins86bird

Good to know. Last I heard they needed a bit of grinding to fit. I have yet to install my 13" C4HD setup which is the same as the 13" Baer.

ok i have the measurements, i took the measurements with the wheels spacers laying on the wheel...they need the spacers to not rub on the car...if the C5 brakes fit with minor grinding to the calipers so be it...if not what is the largest brake that will fit...
ok the backspacing with the spacers is 5"
the outside diameter is 16 3/4
an inch and a half into the wheel it tapers down to 15 3/8
next measurement i measured the diameter flush with the wheel spacers laying on the wheel which was 5" in and that was 14 11/16 seemed slightly larger then 14 5/8

so it starts out at 16 3/4, then an inch and a half in tapers down to 15 3/8 and from there tapers down to 14 11/16 at 5" deep so what do we have to work with?
