Springs: 12/10 OR 9/7.6 Ride Heights: 105/105 OR 100/105 Shocks (Bound): 8/8 Shocks (Rebound): 5/5 Camber angle: 2/1 Toe angle: 0/0 Stabilisers: 3/3 OR 4/3 I'm not too sure myself. My GT4 disc is a goner for now... Go and try it. I tend to prefer oversteer. And yes, get a full customise suspension instead of the original suspension.

The specs above were for grip racing and for low hp cars. If you used my racing line, you'll see it's at neutral handling but braking too late makes it unbalanced and causes you to understeer. I had a 1980's silvia K and it has the same specs. There's little oversteer but not a lot to make you spin out or help you drift. |

Try Initial: 15 Accel: 40 Decel: 10 as a start, and tweak from there, seeing what works, what does. Also rear biased brakes will help bring the back out a bit during braking, killing off some corner entry understeer. Oh, and try Sports Soft tyres too, I find with low HP, S tyres are pretty much perfect. R tyres would be too grippy, and probably causing you to understeer. |

Actually, the set-up I had posted was actually my normal grip settings. I tend to brake first before turning in hard before adding in the gas. The rear would slip a little but not to the point of spinning out; it's just enough to change the direction of the car. And well... I'm quite a aggressive driver in GT4, always pushing the cars' abilities beyond the limit | ||

IDW Goldmember Group: Advanced Members Posts: 1,133 Member No.: 2,798 Joined: Aug 25th 2004 Location: Levanger, Norway | You should take into consideration I am a GT-R driver that relies on some power oversteer upon corner exit. So I added some settings to accommodate that as well as improving cornering speed overall, I upped the limit with 10 Kph as well as quickening the turn in response. I ran the test on Grand Valley speedway and my first annoyance was the gearbox, it is a bit out of tune when it comes for that engine, but it is doable. Anyway, here is what I did: Brake balance controller: 12 front 10 rear (Slight locking, but at higher speeds it slows you down quickly and can be used to quicken the turn in, it is a lot sharper on turn in with these settings, may lower them to improve braking at lower speeds and lessen the turn in response.) Suspension setup: Spring rate. 9.0 for the front 7.0 for the rear. Shocks are left at 7 Front camber 3.0 Rear camber 1.0 Toe settings front 0 Toe settings rear -2 Stabilizers front 7 Stabilizers rear 6 The rest is left according to original specs, time improvement with this setup over the other one was 1.2 seconds. |

These are the change I applied. Spring settings: 8 6 Camber angle: 4 1.7 Stabilizers: 6 5 and one question, for the brake controller, the higher the level, the faster the car slows down? by the way, the car understeers on that crazy loop on autumn ring and still need to adjust the lsd to clear it without a problem. I go through that loop at an average of 85 kph. This post has been edited by Red Dragon Racers Leader on Nov 17 2007, 01:58 PM |

Higher value does equal better braking, but they have to be balanced, If not then they have little to no effect. Furthermore my experiments has shown little gain of more than 3.3-5 degrees of camber, mainly adding too much will ruin braking. The understeer upon corner entry can be helped by toeing out the front (Negative value) | ||

It took a lot of practice to make that time. I tried it out again on Tsukuba and lowered the rear camber by .7. The time was 1'01.6 something.

IDW Jr. Member Group: Members Posts: 50 Member No.: 24,150 Joined: Apr 24th 2007 Location: Update Profile | No, I actually can't afford them, but what if I did? I also don't like the size of the wheels. It's so unrealistic. The first time I used them at some Auto Show, I didn't do well. It felt really strange with such a small wheel that doesn't turn back after letting go like the initial d steering wheel. |
