Ive got 1000 pounds to spend

[Brucefil]

To get the best improvement in lap time should i buy

1. A lsd and light weight fly wheel
2. Bump steer correction kit
3. Power steering, Air con and heater removal.

My only criteria is which one of these will improve my lap time on a mix of tracks (fast flowing, long straights with sharp entry and exit and circut where your constantly turning)

What track? And what's the current spec of the car?

Apart from LSD all is possible for under 1k.

Hi..

Out of the options you've listed it's a tough one... as a side note I'd always start with tyres, buying the best ones you can, then i'd concentrate on removing weight (will help everywhere, accel/cornering/braking) then worry about brakes/power ... getting back to it do you mean geo correction as part of the bump steer correction? Or just bump steer correction on its own?.. lsd will help with traction out of the corners, bump steer correction will help straight line stability and with cornering and lastly the delete kits will give a small BHP increase but will also reduce car mass, which will help all aspects as I said before.

If you did mean geo correction (for lowered cars) then I'd do that as it will be worth more lap time than the weight reduction of the delete kits and/or the LSD

Timo your blog is superb. Sorry forgot to mention have upgraded ftont brakes to brembo 4 pot. Control tyres are used (yokos) so nothing i can do there.

Another question in upgrading the brembos i was locking up as balance was out using standard system with dot5. As a quick fix do i just buy a brake balance valve and connect it to the rear system or front system?

Sorry forgot to also mention min to ground clearence is 100mm so plan to run 100mm at the front edge with a splitter and have the car at 1-2 deg rake.

Thanks mate .. ah ok well that ticks tyres off then.. I'd get the geo correction kit which sorts bump steer and corrects the roll centres... it will make the car more stable on the brakes so you can brake slightly later, turn in will be improved and traction will be improved, even to the extend u think you have an LSD diff fitted.. and you'll be faster down the straights as you have exited the last corner quicker... win win .. search ACS Motorsport on Facebook or on here.. kits are great.

Are you locking fronts before rears I take it?

 

[Brucefil]

Yes locking the fronts

Do you still have the standard rear brake lines and pressure reducer fitted.... under the car around the rear subframe.. normally connected with a link to the subframe

 

[Brucefil]

Yes i think everythongs standard

Diff. Without question.

@JamesBryan just had one put in his and the difference is incredible. All the traction you ever need for mid corner grip and getting a lot of exit speed.

LSD 100% about the best upgrade you can do to a FWD car. Magical device.

Take it to Mark Fish in Harlow

LSD, mine made a big improvement on my 172. Not sure you'll get one for under 1k though.

 

[Brucefil]

From australia to mark fish?

Sell your bilsteins, use that money and your £1000 and buy some AST's.

Then buy a diff.

 

[JamesBryan]

Diff will be a grand or so. If you can do all the fitting/work yourself then you'll save a fair bit.

 

[Goodj]

Splash it all on track time and replacement rubber, discs n pads

 

[White16valver]

How about some driver training? A grand should buy you some time with one/some of the best drivers out there.

A banging weekend at Darwin Triple Crown?
