what you need is the S-13 coilovers themselves, s-13 hubs and try to get the matching brakes/rotors for the s-13 unless you want to go to r32-34 items ( re-drilled rotors to 4-stud with larger rims needed)

optional items: s-13 tie rod end ball joints re pressed into your r30 items, r30 adj strut tops suited to the coilovers you get, s-13 adj tops have to be reversed so you loose most of the -chamber adjustment.

they all just bolt in using the r30 Lower control arms, but you have to wind out your steering rack ends and get a wheel alighment..

it can't be done without the hubs as the s-13 use seperate hubs and shocks..

the strut tops don't have to be changed as they fit but only allow a small amount of chamber adj using s-13 tops, if you are wanting lots of chamber then look into cusco r30 strut tops...

you can just see here where the coilover bolts to the hub if the brake line wasn't in the way.

I was told that you cannot repress s13 tie rod end ball joints into r30 ones.

To make the r30 tie rod ends fit the s13 ones you can counter sink a hole in the top which enables you

to get the nut down enough onto the tie rod end so you can get the split pin through.

Only has to be drilled a about 3mm.

whats funny with the s-13 tie rod end and r30 tie rods ends is that they look exactly the same it's just the s-13 items are tapered to slot into the hubs, and the thread is wrong direction to just bolt them onto the r30 rack ends.

i never worried as i never went with the coilovers in the r30, i put them in but never drove the car with them in. you could just put the king nut on upside down??

Im not sure? Never thought if putting it upside down. I think it will still miss as it will go on too much missing the hole again.

Its an easy fix anyway. Counter sink a hole just about 3mm down. Then it will fit perfectly. Easiest way i worked out.

Retaining the r30 tie rod ends.

the conversion is easy enough to do withough any hassle. Only thing is waiting for the right hubs at the right

price.

i managed to pick up a set of hubs, sr20det calipers and discs, s13 rear discs with s15 rear calipers for $150!!!

Check the nissansilvia forums. there are always guys doing s14/s15 5 stud conversions selling their s13 gear!

u could cut and weld the coilover to the strut so keep the std brake/hub set up. save stuffin around with s13 hubs etc. but yea stuck with crap brakes...

to do that right would cost more than the hubs, a lot of stresses go through the struts and you don't want that the crack going around a corner..

you be better off getting r31 struts and having the threaded sleves welded on to convert them to height adj with some good shock incerts.

what you got to think about is "why s-13 coilovers" what do you want them for:

height adj - for about 400 you can get height adj kits from Noltec / cusco, $500 a bloke on ebay will send you a front set of struts already made with springs and adj strut tops, $800 and they come with new incerts, These are for and r31 but the only difference to the r30 struts is they are shorter by 30-40mm...you would have to get a set of r31 rotors and calipars but they are bigger and better then the r30 items so thats a plus...

i was gonna do it my self so work out cheap as. dw i no what im doin lol.

could use z31 struts their shorter then the r31s by 1 or 2" i found out when put them into my r31. also get nice brake upgrade.

gerryb on s12 site has done it in his s12 im pretty sure. but yea would have 2 go coilover sleve kit of course cos dont think it would fit in the strut tower, spring is even wider then the r31s.

thing on re pressed ball joints, heard couple of stories of them coming out. think thats how bigjc guy stacked his r30. is there a different way?

cheers...

      The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.

      When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.

      Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.

      This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.

      Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
