93TurboSi

Does any body know of any big brake upgrades for us poor souls with the 9.5" fronts. I have a 93 Civic Si without ABS so i have the smaller 9.5" front rotors instead of the larger 10.2" and so i am having trouble finding a big brake upgrade. any one else find solutions to this problem.

you can upgrade to integra gsr brakes (or itr)

or check out the 11" brakes at http://www.fastbrakes.com

or AEM but that is a bit pricier

what is the largest kit that will fit under 99/00 15" OEM Si wheels?

93TurboSi

Actually i can get the AEM kits with OEM caliper for like a third of the fastbrakes setup. The problem is that the AEM only seems to make kits for the 92-95 civics that came stock with the 10.2" front rotors.

I would have to replace the steering knuckles with ones from 92-95 civic with ABS or 94+ integra for the AEM to fit.

did you upgrade the Brakes on your CX? what did you use?

the fastbrakes 11 inch rotor with wilwood caliper will fit under with a 5 mm spacer.....

i didnt know that...

i actually got gsr brakes for a pretty good price through a member on honda tech. so yeah, in order to run the aem you need the gsr swap then. if you look around you might find some pretty good deals (from the gsr owners that upgrade to 5 lug). good luck

Here's a dumb question,
I have a 94 Si with ABS
what size are my front brakes?

93TurboSi

they should be 10.2 inches. but you can always just measure them.

I found a company that makes a big brake kit for the 9.5 fronts...

why do you need bigger Brakes, I see you have a turbo car. Have you tried new rotors, new fluid and better pads? This made a huge differnce in feel and brake effectiveness on my cars, howver niether of them are turbos, jsut a suggestion, for brakes talk to Andie Lin at http://www.coblatfriction.com or Matt Nicholson @ http://www.carbotecheng.com you can also pm himas he is on this board as MaddMatt.

The brake kits I am comapring before purchasing:
I want to stay with a kit that fits under a 15" wheel (currently Civic Si wheels) and offers good street driven reliability. Maybe some of my notes will help someone else spark some good questions.

Fastbrakes 4pots - great kit but I do not like the fact that the Wilwods have no piston dust seals. Plus I will not have to change to 10.5" brake steering knucles.

Fastbrakes oem upgrade - I am interested in this because I will not have to change to 10.5" brake steering knucles. But I'm still waiting for an answer from Fastbrakes if you can later add Wilwood calipers on the oem adapets or if you need to add calipers and adapters.

Baer SS 2 pots - still waiting to see if the calipers have piston dust shields.

oem integra set-up - would require changing the knuckles, which I would rather not do because of the new wheel bearings, ext studs, and ball joints.

I'm probably leaning towards the Baers or the Fastbrakes oem kit.

I feel like i have plenty of stopping force but at high speed the brakes fade very quickly so bigger brakes would take care of that easily. also the tiny little 9.5" brakes just look way undersized in side a big set of rims. what sucks is i found aem kits for about $280 which would have been a super cheap upgrade but of course they don't have them for the 9.5".

do think i would have to change out just the knuckle to fit the aem kit on or would i have to change out the knuckle and caliper from the 10.25" fronts?

My Brakes used to fade pretty easily on track, all I did was flush the fluid and remove my dust shields and I have not had a problem since with Fadding and this inlcudes several tracks where I am stopping from 120 to about 60 lap after lap. I run Dot 4 fluid and carbotech panther p+'s and still have not had any fading issues.
I am just sharing my expereince in the hop it my save you money, I would out new brake fluid in the car and remove my front dust shields and see what happens.

i think a GSR suspension swap would be the best/cheapest upgrade. the Si(EX) coupes share the same rotors as the GSR so you can swap calipers for a marginal inrease in stopping power.

i swapped mine and added Hawk street pads. works wonders. i had KVR before.

I'd also recomend going with cross drilled rotors... they reduce fading if not eliminate it... I get on my brakes hard a lot and NEVER have fade anymore...

Although that doesn't solve the size issue...

just figured I'd share the link to the 9.5 big brake kit that I stumbled across.

Cross drilled rotors are not crossed drilled to reduce heat, in fact cross drilled rotors do not have as much surface area to help get rid of heat build up, rotors where crossdrilled to eliminate outgassing, which pads no longer do everytime the heat up.
Here are some links to back this up
http://www.teamscr.com/rotors.htm

And from this aricle on http://www.stoptech.com/whitep...1.htm
"Unfortunately the drilled holes also reduced the thermal capacity of the discs and served as very effective "stress raisers" significantly decreasing disc life"
And a nice pic of a porsshce 959 rotor http://audiport.com/959/DSCN0266a.jPG

And to follow up an article from will wood.. http://www.wilwood.com/faq.asp#question7
Slots or grooves in rotor faces are partly a carryover from the days of asbestos pads. Asbestos and other organic pads were prone to "glazing" and the slots tended to help "scrape or de-glaze" them. Drilling and slotting rotors has become popular in street applications for their pure aesthetic value.

So save your money and by solid venter rotors, I have used cross drilled rotors for a short time and they do feel differnt/better however they do not cool any better and are more prone to failure

Where did you find AEM BBKs for $280?

Have you thought of just replacing the rotors with like EBC Slotted and dimpled ones, Greenstuff pads, and Goodridge lines? Even though they are the same size I am sure you will get more performance out of that setup.

no thanks

NonovUrbizniz

Thanks for the usefull post...

the poster requested a link to a big brake kit for 9.5 fronts... I found one for him....

I didn't post the link for you.

I also wouldn't want 18's to have bigger brakes.... BUT... MOST companies say min. 17" or 18" and MOST times there are several 15 if not 16" wheels that you can stuff them under...
