Current Spec
Pirelli 58 3 door.
Chassis :
Bilstein PSS10, WALK, TT alloy lower arms and ball joints, TD 8x18, VWR front brakes, neuspeed ARB's, All camber and ride heights tweeked adjusted and now finished.
Engine:
TT bottom engine mount, Miltek TBE, REVO stage 2, K&N panel filter, Forge DV, Neuspeed quickshift.
I am unhappy with the vibration of the THS bottom mount, would like to see how I can reduce wheel hop and manage vibration ?
Quite interested in Whiteline bumpsteer kit to be fitted at the same time ?
I also find the engine seems particularly sweet and crisp most of the time but occasionally seems a little fluffy, is it worth changing the Forge DV for a late original DV ?
Tks for thoughts
-
IMHO I would be running the latest revision DV over the Forge one. :happy2:

What reason? Thanks :happy2:

Have you thought about running some "semi-track" tyres? More grip should equal less or no wheel hop.
Yoko ad08 or maybe Hankook rs2?

Stickier tyres can create more wheel hop I've found. All depends how much power you are running too.
The hankook rs2 tyres are now discontinued. The rs3 replacements are not UK road legal. Damn annoying as they were a top cheap track tyre.

@ OP
What was your final Geometry settings?
I have the TT arms & ball joints going on this week, along with the bumpsteer kit
I'm lowered on 30mm H&R springs, Bilstein B8's and running 7.5J 18 OEM monzas with WALK also
Any help would be much apperciated as i've read all previous threads on this subject but am none the wiser :stupid:

Yeah i suppose your right. I was just thinking along the lines of.... Sticky tyres - more grip - shouldn't lose traction as easily.

Well, I had one on mine did loads of logging and when compared against the latest oem dv I saw that the OEM was holding boost better than the Forge. Could be a nuance on my car, so not necessarily something that everyone would see. This was particularly at the top end.

More grip will cause the engine to rock back more violently on acceleration which causes the 'hop' sensation which breaks the traction of the tyre, so ECU cuts power to regain traction, engine goes forwards again for the sequence to repeat.
I definitely had more wheel hop when i moved to stickier tyres.

Thanks I changed the spring on my forge but may try a revision DV to see if there is a difference
What kind of pressures are you getting & what state of tune? :happy2:

1.68 bar, ST2+ on ko4 :happy2:

If you're happy at that I'd willingly try one to see the difference...

Dom, hi
I'll check the one that came off, a late 08 Pirelli might have a late version ?
-
Possibly - will be obvious once you see it as ETKA PN clearly visible :happy2:

How do you calculate the Ride height? Form where to where?
I also have the PSS10 with similar settings (just 1 click harder on the rear because I haven't got ARB) and I would like to compare if height is similar.
-
Sorry, the ride heights are from the wheel centre to the archlip, straight up. You will find small differences with wheel offset (as the wheel centre might be marginally more in or out affecting the length fractionally)
I put the start of the tape on the wheel centre, go straight up and where the tape hits the bottom of the arch take a measurement
Stock ride heights are 360mm ish. My measurements are currently 342mm F 326mm R
-
I have always read that back should be higher than front (just 10mm)... What do you think about?
-
I have tried a lot of options and did not find the Golf perfomed well nose down. It simply understeered more........
Plus the front geometry does not perform well too low. I did try the back at 330 and 335 and 350, it lost the balance. I would like to run the rear a little higher but as I move from the current heights the balance and grip is reduced for my set up and my handling preferences

Carrera thanks sent :drinking:
