Hello all.

I am in need of some good rotors for my 2003 STR. I don't want any of the cheap nonsense, but at the same time I can't really break the bank at the moment. I know that Centric is a fairly big name in brakes, but has anyone here actually used them? (I'd be especially grateful for feedback on these rotors in an STR.) I found a set of all 4 Centric Premium rotors (correct sizes too, which is uncommon as any other STR drivers undoubtedly know from online searches) for $416 shipped on Rockauto.com. This is roughly half of what I'd expect to pay for Brembos, so if these are any good, I'd like to give them a try.

Thanks in advance,

 

I put Centric rotors, rebuilt calibers, and ceramic brake pads on my xk8. fit perfectly and no problems. I also got them from RockAuto...best prices

 

Just did the brake job not a month ago! I was in the same position as you, didnt want to break the bank on something that probably needed chanign in 12,000 miles or sooner. I Used Centric rotors and akebono pads on all sides. Works perfect! I used Rock auto for the rotors (380 shipped for all 4, Shipping took like 5 days) and got the pads off amazon. Good luck!

 

Any chance one of you could post a part number for the STR rotors?? It's very hard to find the correct size rotor.
Thanks!

Also post whether you have Brembos when posting a part #
(The rotors are a different size Brembo & non-Brembo.)

 

This topic really does get repetitive.
Someone from the Atlanta area just put these on a Brembo equipped STR after getting the wrong ones initially. I think he reported back about 2-3 weeks ago.

I think I've posted 4 or 5 times the Centric listing and there are at least a a couple guys on here who have long term miles on these rotors.

SEARCH!!!

But here: http://www.centricparts.com/index.ph...d=51&Itemid=85
Click on the images to get the specifications

And a cheap price as well http://brakeperformance.com/site/bra...1410&ad=direct

 

It does get repetitive BUT most of the data is flawed or wrong. Example: the rear rotors from that first link you posted look to be the wrong size (330mm is 30mm too big) for my 2004 STR (best to call it a 2003 since it was built then and is before the VIN change in 2004).

The second site doesn't appear to give any specs so that would be worrying!

 

Thanks for the Centric link but it states they DO NOT sell to the public. So where do you find them?
They do seem to have the correct size front and back rotors for my 2005 STR!

Well that is strange. The JTIS I Have shows 365MM front and 330MM rear for the cars with Brembo rotors in 2003.

So I'd have to assume they fit the car he's asking about.

It's not formatted but here's the data:

Did you try the second link?

 

The question gets asked so often so maybe it should be a sticky????

Bob S.

 

Oh dear!! The Jag S-Type brochures I posted recently show the Brembo rear as 300mm. I wonder which is right, JTIS or official brochure?

I despair. No wonder this comes up often.

 

For my 03 STR with Brembo Brakes the parts i used (installed and working right) are:

Front:CENTRIC Part # 12020018 (365mm)

Rear: CENTRIC Part # 12020019 (330mm)

I Checked, it should work with 03-05 STR, 05 SuperV8, and 04-05 XJR

Cheers!

*part numbers are from www.rockauto.com (they list the same as Centric themselves)

 

And since someone asked ... how are they doing and how many miles?

Bob S.

 

I've been eyeballing the Centric BLACK Rotors.. Im curious how long they stay black. That would be sick!

 

Usually the black will wear off from the pad contact, but the rest of it will stay black. Looks better than rust anyday

 

Well when I emailed Centric, they said its black through and through not a coating, Im still spektical as expensive as they are.

 

It wasnt Centric, I dont recall who it was I have thier info at work, and if I can find it on my desk on friday I'll post them up.

 

Thank you all for your replies. I know that several questions are asked about the STR rotors, and I have gained much technical knowledge from the other threads. My purpose in this thread was to compare quality vs price. And it seems as though the centric rotors may be a wise investment based on response.
Also, since this has come up again: the STR does use 330mm diameter rear rotors. The base S-Types use the smaller 300mm out back.

 

These rotors from brakeperformance.com are actually cheaper than rockauto (free shipping vs ~$80 shipping). Does anyone know how they compare withe the centrics? Or the stock brembos for that matter?

And before I get the typical "go search" response, I apologize for not being able to find these answers but it's difficult to sift through so many threads while working 18 hour days. I have searched, but gave up after about two pages of threads. Perhaps my search terms are off.

Thanks again!
