Glad u like them Dan and used my feedback to help u, yeap cool white is better then warm white....i hope u stuck them on good and used a flexible silicone as this will obsorb the vibration from the car.
Good work but, where r the pics?????

Yep, I used a clear quick drying silicon, fingers crossed they should be ok. Will get some dusk photos later.

19" wheels simply don't offer enough side wall for the tyre to flex enough to conform to the smaller surface imperfections nor isolate the suspension from the smaller bumps allowing it to control the wheel properly. The figure I've come across over and over is 85-105mm is sidewall for a road tyre. For a RWD car rear tyres benefit from a little more side wall than front tyres. Also rougher the surface the more sidewall you want.

Give you an idea what tyre sizes you want -
40 profile 215-265
35 profile 245-300
30 profile 285-350
So to get the tyres in the Z4's arches you're running 17-18" rims.

jonny i was under the impressive you wanted lighter wheels to actually do a complete build on the car along with the turbo , aiming to get as high performance from the car as possible, i wasn't under the impressive it was because people commented on the weight of the BBK???

so if I'm right and you want to continue to build a street weapon that you can really enjoy and lean on definitely stick to getting a lighter rim you'll be surprised how much difference a set will make, they can really add some feel back into the steering too. try and keep to 18s however .

Yes i do want a "street weapon" Byron lol, nothing to do with the BBK i just got thinking about weight as i put them on so then decided on some weight reduction parts.
So is there a real benifit from 18" not 19" as i will need new tyres so another £800-1000?

yes, they are in general lighter, and so much better tyre choice, you'll get a really nice road legal semi slick budget tyre for under 550 quid fitted that will eat a high end summer tyre for breakfast in terms of feel, dry grip.. as your car doesn't see the rain these will be perfect for you ( in the rain/ cold or damp they will be dangerous ), and what i use as do a couple of member on here, bmwz4mc also uses the nankang ns2r and is equally impressed

your car will be an awesome road weapon as its already much lighter than most car on this forum, the wheels will easily negate any bbk related weight and probably net you some decent overall weightless if you get the right rim your BBK will also fill 18s much more and thus your car will look alot cooler too, lol! try and aim for a low 20lbs wheel and sub 20 if you can afford to get into this range, you will notice that for sure, particularly the ride and the overall feel to the steering.

looking forward to seeing this road weapon come to life :evil: :evil: :evil: :evil: :evil: :evil:

if you want light weight and low cost APEX is a total win, their wheels looks ACE , very strong and super light, under 20lbs for 8rc in 18s... they are deep concave and flow formed constructed.

 

[techathy]

Interestingly, if you're going for strong enough for road duty lightweight wheels rim diameter means almost jack. Total package diameter, rim width & tyre width, in that order, however mean more. If you go for the ultra-low load wheels then by going for more rim diameter you get less weight (though don't think about not dodging a pot hole or you'll end up with cracked/bent rims.

Second that - I have a set of Apex EC7 wheels in 18".

If you go for the ARC-8 just check it will clear your new brakes - the EC7 has slightly better caliper clearance.

These Breytons are 16.75lbs in 19" as well......so they are VERY light. Just unsure on 18" or 19" but i have ages to think about it so its cool for now.

bloody hell thats seriously light..... almost suspect light , lol! especially for 19s.... maybe from a fully forged rim. For your road warrior you really want your 18s with that slightly thicker tyre, it will really smooth out the ride nicely too. however 19s can work just as well, but tyre choice lacks and ride suffers.

Tyre choice for 19" on coilovers, whats ur choice? I have 235/35 front ( rubs on turns, well used too but its worn a small part of wheel arch ) and 265/30 rear on MPSS ATM.[/quote]


your current tyres are ideal for the rim size your using... dial in alittle more negative camber upfront and your rubbing will vanish.

Would a touch less off-set help?

Quite ... that is lighter than the drop forged 17" wheels I had on my Elise, which are the lightest wheels I have ever had.

doesn't seem realistic really tbh.

 

[Mark-Z4]

I too am having thoughts on new wheels. I like those Breytons, the firm lines of the wheel suit the Z4.

I'm either...


Painting the CSL's gloss black...the cheaper option but don't know if black wheels will look cheap.

A genuine set of 19" bmw alloys, 313's Or Ronal M wheels found on the E98

Aftermarket set, like 3SDM or BBS

 

[mr wilks]

I like them jonny , just not sure id pay £1700 for them :wink: i had a set of Breyton 19s last summer & they were crazily light to handle but the downside was very easily buckled or split depending on how much rubber you can wrap them in . They also drop big time in value should you decide to move them on which is quite likely
RE the lightness thoughts ? I really wouldn't get hung up on it for the demands you ask of your car .
Are you going to continue the process & strip out all other excess weight ? Lighter seats ? Get rid of sound deadening & carpets ?
With your silver car id be looking at these puppys & you could afford them sooner being half price

or the real ballers would go for....


the real deal BBS Fi. proper forged units these really weight nothing... and are available in bmw fitment

Yeah, they're lovely - think I saw them before at something around £5.5k a set - and that may have been ex-VAT :!:

Nooooooooo.

[ba3bas]

1700 for a set of breytons??? No mate.

However i do like them, but at that price much nicer and rarer wheels available.

As mentioned, if you want light good looking wheels, go apex and save yourself a few quid, but a few have them now so i personally wouldnt run them for anything but a winter or track set.

Still follow your heart as i cant talk.

I have 3 sets of wheels for the Z currently.

 

[aquazi]

I like them... But i'd go against the grain and say stick with 19's they look so much better... And your hardly going to race it to benefit from 18's

 

[ba3bas]
