upgrading starlets brakes topic, opinions expertise be helpful.

ebay, be weary tho, jdm and early spec uk st185 come with the smaller twin pots the single pots only come on the later uk spec st185. Id sign up to a celica forum and ask around on there

 

[jayc-glanza17]

cheers for heads up, did read that on gt4oc earlier.
u got a pic of how yours fits under your wheel at all???

 

[pockrockgtti]

I dont im afraid, ive got 16" wheels and theres loads of space. My mate also has the same brakes on his starlet, and he has a set of 15" team dynamics pro race 2. I 'd say u need at least a 15" rim.

Just as an Idea - I don't know if any discs from Ford would fit our Toyota (may be the holes would have to be drilled to fit Toyota), but the calipers might do??? Either way - a mate of mine fitted 300mm on Fiesta with 15" wheels! the calipers has to be shaped to do that, but it is possible! I think he said those brakes from Focus ST!

300mm sounds good enough and fit 15" pretty difficult! ALso look at the price! But I don't know if that would fit our cars, however that would be the cheapest upgrade!

 

[jayc-glanza17]

anyone got thoughts on the ford side????

not sure on 300mm discs on 15's which i have 15s.

what other calipers bolt straight onto a starlet anyone know????

 

[sx_turbo]

st165 discs

02- corrolla discs (25mm thick and 255mm diameter)

6mm spacers to go behind discs, and longer studs

should in theory all bolt straight on, this is what i'm thinking of doing, but i need to finish restoring the mini first before i start playing around with mine

 

[sx_turbo]

or

just use the celica st165 disvs, redrill the holes for the 4 stud fitment (as they are 5 standard) and get 3mm spacers to fit behind the disc and you should be able to get away with putting longer studs in

 

[jayc-glanza17]

the astra disc option seems fairly cheap and easy to do as well.
as u work in motor factor trade ricky,
you havent got good places to buy st165 or 185 calipers???

U could also fit the twinpots using a set of discs off another vauxhall, i dont remeber what model there off, but from memory there the exact same dimensions as those 280mm i mentioned earlier but are a 256mm diameter. If you used them you wouldnt need to put a spacer between the hub and disc. No longer wheel studs req. All youd need to do is make a spigot exactly like i explained in my previous post and it would simply bolt on.

 

[jayc-glanza17]

yh our set up looks good, and like u say stops better then stock and difference is noticeable,
arent those other discs fom a mk4 astra u mean matey???

I'm wondering a lot of people have done st185 conversions using the single pot calipers with carriers some have gone for the astra 1.7 cdti disc. but i have a question for those who have done the conversions, which is better single pot or twin pot, if thats the choice also if you opted for a disc which one would it be:

astra disc http://cgi.ebay.co.uk/OMP-280mm-Front-Brak...=item519654b9af
Part Number: TFS/2145Diametro esterno (A) (mm): 280
Spessore disco ( B) (mm): 25
Altezza totale © (mm): 42
Posizione disco: Anteriori
Numero fori: 5

corolla d4d http://cgi.ebay.co.uk/Corolla-Verso-2-0-D4...=item19b9063ee1DescriptionFRONT BRAKE DISCS , DIAMETER 275 mmTHICKNESS25 MMHEIGHT49.2 MMSolid/VentedVENTEDCENTER DIAMETER MIN THICKNESS23 MM


levin discs http://cgi.ebay.co.uk/TOYOTA-Corolla-Levin...=item4150db40a8
Type / DiameterVENTED / 258mmThickness / Height22mm / 48mmStud Pattern + Holes4


(please not links are just for dimension sizes that are written)


now for the question im trying to ask is there a way of doing a twin pot conversion using any of the above disc's which wont need spacers ?

as for the st185 you dont need spacers all you do is use the astra 1.7 cdti discs which has been tried and tested all you need to do is get a spigot ring made to reduce the center bore of the vauxhall disc from 60mm to 54mm and it all bolts on.

I'm going to get some calipers and discs from scraps to see which is better without modification i will be getting one of each caliper off the toyotas in the breakers yard and see whats best and i'd use yellow stuff as they are excellent when used hard as well

 

[jayc-glanza17]

when u likely to know between twins or the st185 single pot???

it is a question i wouls like to know the answer to, any thoughts on this questions guys???

 

[GlanzaV.Tee]

i cnt give my options on that yet give me by end of the week to source them from my local breaker and then i will get back as i want something without making a spigot as well a str8 bolt on kit without hasstle unless i find someone to machine some for me and i can build up kits but i will try and test see what i can dig

 

[jayc-glanza17]

it be nice to know or even get a list cimpiled for sigpot and non sigpot needed discs,
so people could refer to it when they get into out predicament.
ive heard that mr2 calipers are similar to levin or something and should be able to bolt on.
not sure what mr2 tho.

 

[GlanzaV.Tee]

i will b gettin mr2 calipers as well as celica and other jap calipers and i will do a write up on which one needed and how to do it i want to do a non fabricating straight bolt on lol this is going to be a big puzzle

Japanese brakes are pretty shit full stop! No matter the make - talking about the standard brakes! The racing one would cost a fortune but are they really worth every penny? doubt it!

The best brakes would be German - max speed limit in Japan is 110 kmph (around 70mph), max speed limit in Germany - no speed limit and many cars are designed to stop from over 200 kmph - look at any decent German cars - the brakes are massive! Even the bloke from Australia said - the brakes in Europe are like racing for us!

My point is - if all of us look for a cheap and DECENT solution we need to look at the European car makers and see if something will fit! 280mm will fit 15" no probs and that would be the discs of the Ford Mondeo for example!

I've driven a BMW of a friend of mine and blind me the brakes were in 10 times better than I've got at the moment (I have EBC Grooved discs, Mintex Racing pads, Braided lines, Dot 5.1), I've only touched his brakes and I could kiss the windscreen if it wasn't for the seatbelt - seriously impressed!!!

 

[GlanzaV.Tee]

yeh i know all that but its not about about germans or jap its finding a suitable bolton kit, the calipers will have to be from a jap car as we dont want modification on brackets, but the disc aint much problems as we can source them but when i get to the breakers i will see which would suit and clearance for 15" rims i have 2 rims i can try kei and o.z also have the 16's but i am trying to source something that wil fit under 15's i wont have my car soon but its stil not going to stop me from helping others cheers for info paul

i've got a bmw as a side car for emergencies its a 318is coupe and braking on it is crap lol rear handbrake shoes fade like icing on a cake


but i will do good research and report back for all you guys

 

[ramses974]

Go get yourself a set of single pot calipers off a st185 celica, its the besy upgrade i ever made. They more or less bolt on if you know what discs to use. All you need to do is get yourself a set of 280mm discs off a Vauxhall Astra 1.7 cdti and make sure they are the 4 stud ones like this. If you use those discs u dont need any longer wheel studs, and you dont need to place a massive spacer inbetween the hub and the discs, like you do if ya use the corolla tsport discs, all you need to do is get a spigot ring made to reduce the center bore of the vauxhall disc from 60mm to 54mm and it all bolts on.

good idea
but if i use standard Toyota Wheels they will not fit due to the center is 54 and not 60

 

[pockrockgtti]

good idea
but if i use standard Toyota Wheels they will not fit due to the center is 54 and not 60

Theyll still fit, the spigot is only the same thickness as the face of the disc. So that 54mm lip on the hub will still be there for you to be able to fit ur wheels.

 

[jayc-glanza17]

yh the point of this thread and the opinions is to improve the braking of a starlet considerably without costing an arm nd a leg.
also as bolt on as possible is a good solution, and if there bigger brakes we are fitting it improve the strlet braking capacity, which is our aim.
would like to know your finding glanza v tee....

seriously st165 twins or st185 single, which would give braking force????
