Title: PPP subframe
Post by: grantvw on May 17, 2011, 09:20:42 PM
Hello to everyone i just wanted to put a post on to back up that if you have a straight car the subframes will bolt on without too much trouble mine has gone on my loon without having to elongate or drill any extra holes or use big repair washers hope this helps people and gives people more convidence in buying a subframe as the do fit like they are supposed too Cheers Pete

watch out while on full lock though if youve got brand new wheels like i had, it ripped all the new powder coating off the inside of my wheels. :'(

Ashame we don't all have nice striaght shells! Had to retap on of my holes and was a bit of a bastard to fit but it would be impossible to make a frame that fits all shells as most ofthem are a little bent from hitting kerbs acident damage or just being old so I wouldn't of blamed ppp for having to fiddle about to make it fit. Have to fiddle with most things to make them fit when modifiying Well that's what I've found anyway

if you take your time and have some patience you would get them to fit any straigh car without issues people have got to remember there as tightly made as they are for a reason and thats because there effectivly holding your chassis together and if they had movement they wouldn't be doing the job they were made for  ;)

Hmm so the PPP ones scrub the rose jointed arm aswell on full lock dam, thought it was just the pps ones!

my PPP one doesn't scrub the wheels with either my 14" or 15" wheels on.  Liam must have funny offset wheels I reckon

But you're running wheel spacers aren't you Hayesey?
It's a BRILLIANT frame, I am very impressed by the whole package and the quality of workmanship, but without spacers my 14x6" ET38 'Scalas' do scrub the arms on full lock. The castor is adjusted to match g-ladseite block measurements. Only rubs a little mind. I've some 5mm spacers to try and resolve it.
Mine is one of the early frames, but I don't know if it makes a difference.

In fairness I'd like to point out that my frame is also 2nd hand and Yoof did mention to me a while back that one of the previous owners might have modified the mounting points for the arms.
Title: Re: PPP subframe

yeah that is true, I am running 10mm spacers on the front

Well i had mine on for nearly a year now and its been fantastic untill yesterday when the special gearbox mount sheared at the welds, have emailed PPP to see if there was a warrenty or if i can buy another if possible.

Grant - sorry to hear that.

We haven't received an email from you yet, but if it is a PPP frame, please send photos of the frame and damage to: enquiries@poloperformanceparts.co.uk along with details of when you bought it etc. and we'll sort things out for you.

My frame also rubs on 14x6 et 38 wheels. Ive had my wheels balanced in the centre of the barrel now and it seems to have fixed the worst of it. It's not a problem for sure.

If people could post up wheel/tyre combos that do/don't scrub that would help out alot.

195/45 14x6 ET33 Doesn't scrub  :)

Not sure about my current combo...

That's good to know, sounds like 5mm spacers on 14x6 ET38 should be all good then :-)

Edit: Useful info...
Wheel size: 14x6 ET38
Tyre size: 165/60/R14
Wheel weight location: Inside the wheel, not the lip
Rubs: On the wheel lip only, tyre seems OK.

That tells you how close it is TBH, if Yoof has run 14x6 et 33 no prob and I'm getting slight interference with ET38 there aint alot in it.

Wheel size: 14x6 ET38
Tyre size: 195/45/R14
Wheel weight location: Inside the wheel, not the lip
Rubs: On the wheel lip only, tyre seems OK.  Will knock wheel weights off if placed on inner rim.

Exactly, which is why I'm not at all concerned to be honest. It's a very small issue with an otherwise massive improvement to the car.

I run 14"x6" ET38, 185/50 R14. I get a small amount of scrubbing on one side, was the same with 13"x5.5" ET38. My current frame is the original prototype, so the "production" frames were given a bit more clearance - but there's a compromise to make with pick-up point position and gearbox clearance.  :-\

Grant - got your email, we'll get back to you by the end of the week once we've spoken to our supplier. Sounds like the pot hole impact broke the weld - I'm still surprised though, as Yoof and I have tried really hard to break our frames in testing!

5mm spacers on the front resolved the scrubbing for me :-)
Title: Re: PPP subframe
Post by: Yoof on June 13, 2011, 04:24:06 PM
So effectively ET33 now then Chris?

Seems 14x6 ET33 is the magic number...
Title: Re: PPP subframe
Post by: cheys03 on June 13, 2011, 06:45:17 PM
Yup :)

It's weird in the few weeks since fitting the subframe and having to avoid full lock, it now takes concious effort to remember to use the full range of the rack when manoeuvring ::)

Fitting guide now here:

I'll upload more pictures soon... Any further hints/tips anyone has whilst fitting frames please let me know and I'll update it to help others.

Where are we talking about the wheel scrubbing? In the actual inner arch or the TCA on the stage 3's?
I'm running a stage 2 frame with G-lader blocks, and under hard cornering the drivers wheel will scrub the inner arch, doesn't appear to be on the tyre, but on the inside rim of the wheel.
I'm running BBS Ra443's
Wheel size: 14x6 1/2 ET38
Tyre size: 195/45/R14

Thinking some 10mm hubcentric spacers maybe be in order, but will then have to look at the outer arch!

Running ppp wishbone conv.
175/50/14.  Wheels 14x7 et43? Am pretty sure anyways Brock b5's

Also have standard mk3 Ibiza gti alloys 15x6.5  ( 195/45/15 )
No rubbing... Apart from high intensity driving but was resolved with slight arch rolling.
Down about 70/80mm front n rear on kw suspension

Bloody hell Terry! ET43 and no wheel to compression strut contact?  :o

I'll start a list of wheel combinations that touch the compression strut, will give people a better idea if they'll need spacers or not.

I think it is :s
You've worried me now....
I'll double check and many post a wee pic

No, I was talking out my arse :(
